DescriptionThe PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default， each channel is driven at 330mA； that current can be reduced by either presenting an analog voltage or a PWM signal to the board. Version 12 of the board adds a solderable jumper that can be closed to increase the maximum current to 660mA. The new voltage regulator also increased the voltage rating on the various components on the board， allowing it to be used up to the full 36V rating of the AL8805 part.Three signal inputs are provided for dimming control. You can use the PWM signal from an Arduino or your favorite microcontroller to dim each channel individually， or you can tie them all to the same PWM for simultaneous dimming. Dimming can be done by an analog voltage(20%-100% of max current by varying voltage from .5V-2.5V)or by PWM(so long as PWM minimum voltage is less than .4V and maximum voltage is more than 2.4V)for a full 0-100% range. A small jumper is provided for each channel to allow you to increase the drive strength from 330mA to 660mA. Two mounting holes for 4-40 or M3 screws are provided on either side of the board. They are perforated so they can be easily snapped off with a pair of pliers， if a smaller footprint is desired.Note：If you're going to use screw terminals， this board uses two different sizes. Check the related products for both sizes you'll need.Note：The PicoBuck LED Driver was made in collaboration with Ethan Zonca. A portion of each sale is given back to him.

DescriptionUSB C is quickly becoming more and more prominent in the maker community because， let's be honest， who likes trying three times to insert USB into a port? This FTDI cable is a USB C to Serial converter which allows for a simple way to connect TTL interface devices to USB. Each 26AWG cable is one meter in length with the USB C side protected by a 2in enclosure.The FTDI cable is designed around an RS232， which is housed in a USB C connector. The other side of the cable is terminated with a 0.1" pitch， 6-pin connector with the following pinout：RTS(Green)， RX(Yellow)， TX(Orange)， VCC 5V(Red)， CTS(Brown)， GND(Black). This FTDI to USB C Cable is also capable of handling high voltages up to 300V max.There are pros and cons to the FTDI Cable vs the FTDI Basic. The FTDI Basic has great LED indicators， but requires a Mini-B cable. The FTDI Cable is well protected against the elements， but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal.

DescriptionThe PQ12 series of micro linear actuators are ideal for applications requiring precise positioning and compact size. Weighing in at just 22 grams， the PQ12 is incredibly light as well as compact. The affordably-priced PQ12 is the most powerful actuator of it's size. This is why it has become a popular choice for OEM manufacturers as well as Arduino and RC hobbyists. Some industries where the PQ12 are in use include：prosthetics， robotics， medical， simulation.The PQ12-R series of linear servos operate as a direct replacement for standard rotary servos. They use the same standard 3 wire connector， ground power and control. Regardless of how you drive your servos， be it with an RC receiver， an Arduino board， or a VEX micro-controller， the PQ12-R servo will function in place of a regular servo， but with the added benefit of providing linear motion. The PQ12-R is available in a 20mm stroke coupled with gear ratio options of 30：1， 63：1 and 100：1 cover a large variety of applications.The PQ12-100-6-R has：a 100：1 gear ratio for maximum lifting force； 6VDC operating voltage； and a servo(PWM)interface. This powerful little actuator can lift 50N(～5kg)!The datasheet doesn't mention a minimum operating voltage， but we've tested this actuator at 5VDC and it seems to work just fine. The maximum force and movement speed are reduced of course.FeaturesGearing Option：100：1Peak Power Point：40N @ 6mm/sPeak Efficiency Point：20N @ 8mm/sMax Speed(no load)：10mm/sMax Force(lifted)：50NMax Side Load：10NBack Drive Force：35NStroke：20 mmInput Voltage：6 VDCStall Current：550mA @ 6VMass：22gOperating Temperature -10℃ to +50℃Positional Repeatability：±0.1mmMechanical Backlash：0.25 mmAudible Noise：55dB @ 45cmIngress Protection：IP-54Maximum Duty Cycle：20%PWM(Servo)signal：Fully retracted：2.0ms @ 50HzFully extended：1.0ms @ 50Hz

DescriptionThe TFMini Plus is a ToF(Time of Flight)LiDAR sensor capable of measuring the distance to an object as close as 10 centimeters(+/- 5cm up to 6m)and as far as 12 meters(+/-1% starting at 6m)! As with all LiDAR sensors， your effective detection distance will vary depending on lighting conditions and the reflectivity of your target object， but what makes this sensor special is its size. Measuring only 35x18.5x21mm， the TFMini Plus allows you to integrate LiDAR into applications traditionally reserved for smaller sensors.Setting itself apart from the original TFmini， the TFmini Plus has been designed with an IP65 enclosure meaning its "Dust tight water resistant"， and also passed the vibration test of drone level， which will greatly expand its application range. The TFMini Plus is easy to power at only 5V and easy to talk to using the UART communication protocol.Important：This product does not use laser light for ranging. Instead it contains an LED and optics. Many such systems are being marketed under the name "LiDAR，" although it may be more appropriate to think of this device as a "Time-of-Flight Infrared Rangefinder". It differs significantly from traditional IR rangefinders in that it uses ToF to determine range and not triangulation ― as is performed by the Sharp GP-series devices.FeaturesOperating Range - 0.1m～12m1Accuracy - ±5cm@(0.1-6m)， ±1%@(6m-12m)Distance resolution - 5mmFrame rate - 1-1000Hz(adjustable)Ambient light immunity - 70kluxOperating temperature - -20℃～60℃Enclosure rating - IP65Light source - LEDCentral wavelength - 850nmFOV - 3.6°Supply voltage - 5V±0.5VAverage current - ≦110mAPower consumption - 550mWPeak current - 500mACommunication level - LVTTL(3.3V)Material of enclosure - ABS+PCStorage temperature - -20℃～75℃Weight - 11gWire length - 30cm

DescriptionThe SparkFun RTK Surveyor is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying， this preprogrammed device can also be used for autonomous driving， navigation， asset tracking and any other application where there is a clear view of the sky. The RTK Surveyor can also be used as a base station. With the flick of a switch， two RTK Surveyors can be used to create an RTK system capable of 14mm horizontal positional accuracy. The built-in Bluetooth(R)connection via an ESP32 WROOM enables the user to use the RTK Surveyor with their choice of GIS application on a phone or tablet. The built in battery allows field use for up to four hours and is compatible with common USB battery banks.This device can be used in four modes：GNSS Positioning(～30cm accuracy)GNSS Positioning with RTK(1.4cm accuracy)GNSS Base StationGNSS Base Station NTRIP ServerIn Position mode the device receives L1/L2 signals from a user-provided antenna and the high-grade GNSS receiver provides lat/long and altitude with accuracies around 300mm.In Positioning with RTK mode the device receives L1/L2 signals from the antenna and correction data from a base station. The correction data can be obtained from a cellular link to online correction sources or over a radio link to a 2nd RTK Surveyor setup as a base station.In Base Station mode the device is mounted to a temporary position(like a tripod)and begins transmitting correction data over a radio or internet connection. A base is often used in conjunction with a second unit set to 'Positioning with RTK' to obtain the 14mm relative accuracy.In Base Station NTRIP Server mode the device is mounted to a semi or permanently fixed position(like a roof)and connects over WiFi to transmit the correction data to a NTRIP caster so that any rover can access the correction data over a cellular or internet connection. This type of base is a very easy way to setup a very precise absolute correction source.Two cables are provided with the RTK Surveyor allowing a user to plug on our easy to use Serial Telemetry Radios or their own radio link. If a local correction source is within 10km， a user can also use their phone to provide correction data over the Bluetooth(R)link(no external radio needed!).Note：The SparkFun RTK Surveyor is just the enclosed device and does NOT include an antenna， serial telemetry radio， or associated mounting pieces.

DescriptionThe SparkFun Pulse Oximeter and Heart Rate Sensor is an I2C based biometric sensor， utilizing two chips from Maxim Integrated：the MAX32664 Biometric Sensor Hub and the MAX30101 Pulse Oximetry and Heart Rate Module. While the latter does all the sensing， the former is an incredibly small and fast Cortex M4 processor that handles all of the algorithmic calculations， digital filtering， pressure/position compensation， advanced R-wave detection， and automatic gain control. We've provided a Qwiic connector to easily connect to the I2C data lines but you will also need to connect to two additional lines. This board is very small， measuring at 1in×0.5in(25.4mm×12.7mm)， which means it will fit nicely on your finger without all the bulk.The MAX30101 does all the sensing by utilizing its internal LEDs to bounce light off the arteries and arterioles in your finger's subcutaneous layer and sensing how much light is absorbed with its photodetectors. This is known as photoplethysmography. This data is passed onto and analyzed by the MAX32664 which applies its algorithms to determine heart rate and blood oxygen saturation(SpO2). SpO2 results are reported as the percentage of hemoglobin that is saturated with oxygen. It also provides useful information such as the sensor's confidence in its reporting as well as a handy finger detection data point. To get the most out of the sensor we've written an Arduino Library to make it easy to adjust all the possible configurations.The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.Get Started with the Pulse Oximeter and Heart Rate Monitor Hookup GuideFeaturesSparkFun Pulse Oximeter and Heart Rate SensorMAX30101 and MAX32664 sensor and sensor hubQwiic connectors for power and I2C interfaceI2C Address：0x55MAX30101 - Pulse Oximeter and Heart-Rate SensorHeart-Rate Monitor and Pulse Oximeter Sensor in LED Reflective SolutionIntegrated Cover Glass for Optimal， Robust PerformanceUltra-Low Power Operation for Mobile DevicesFast Data Output CapabilityRobust Motion Artifact ResilienceMAX32664 - Ultra-Low Power Biometric Sensor HubBiometric Sensor Hub SolutionFinger-Based Algorithms Measure Pulse Heart Rate and Pulse Blood Oxygenation Saturation(SpO2)Both Raw and processed data are availableBasic Peripheral mix optimizes size and performance

DescriptionThis is a foot-long white audio cable that has been terminated with two TRRS connectors at each end. TRRS connectors are the 3.5mm audio-style connectors that you see on some phones， MP3 players and development boards. TRRS stands for "Tip， Ring， Ring， Sleeve，" which reflects the fact that， unlike a standard stereo connector， this actually has three conductors and a ground. Some devices use the extra conductor for a microphone(as in hands-free headsets)or to carry a video signal(as in some MP3/MP4 players). If you're hacking on something that has a 4-conductor audio jack， being able to plug straight in will keep your build clean and simple.We use and recommend this specific audio cable for our Spectacle product line.Features1ft long(30.5 cm)

DescriptionThe MQ-2 is a smoke and combustible gas sensor from Winsen. It can detect flammable gas in a range of 300 - 10000ppm. It's most common use is domestic gas leakage alarms and detectors with a high sensitivity to propane and smoke. The sensing material is SNO2 for which the conductivity is lower in clean environments and higher when smoke or flammable gas is present. A simple circuit makes measuring this change in conductivity and turning it into data fairly straight-forward， but does require some calibration.For easy Solderability； use our Gas Sensor Breakout Board.

With this breakout you can detect surface temperatures from many feet away with an accuracy of ±1.5℃(best case). To make it even easier to get your low-resolution infrared image， all communication is enacted exclusively via I2C， utilizing our handy Qwiic system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.This specific IR Array Breakout features a 110°x75° field of view with a temperature measurement range of -40℃-300℃. The MLX90640 IR Array has pull up resistors attached to the I2C bus； both can be removed by cutting the traces on the corresponding jumpers on the back of the board. Please be aware that the MLX90640 requires complex calculations by the host platform so a regular Arduino Uno(or equivalent)doesn't have enough RAM or flash to complete the complex computations required to turn the raw pixel data into temperature data. You will need a microcontroller with 20，000 bytes or more of RAM. To achieve this， we recommend a Teensy 3.1 or above.Note：The I2C address of the MLX90640 is 0x33 and is hardware defined.

DescriptionThe SparkFun ProtoShield Kit lets you customize your own Arduino shield using whatever circuit you can come up with and then test it to make sure everything is working the way it should! The SparkFun ProtoShield Kit is based off the Arduino R3's footprint that allows you to easily incorporate it with favorite Arduino-based device.One of our favorite features with this version of the ProtoShield Kit is the solderable-like breadboard prototyping area! Half of this area was designed with a breadboard in mind. On the underside of the shield you will be able to see open jumper pads between each through hole to make a connection like a breadboard. Once you add a component， simply add a solder jumper between holes to make a connection. For those that prefer the standard prototyping pads， we left the other side(near the BlueSMiRF and Serial UART ports)as is.We have also moved the prototype testing components(those used to make sure your circuit works effectively)off of the "mainland" of the shield and onto a ProtoSnap styled， removable PCB. On this test area you will find soldering areas for the two yellow 3mm LEDs(as well as pins to control and power them)， two 330 Ohm resistors， a 10K Ohm resistor， and a pushbutton.Note：Since this product is a kit， assembly and a basic knowledge of soldering will be required. The SparkFun ProtoShield Kit does not come pre-assembled.Get Started With the SparkFun ProtoShield Kit GuideFeaturesArduino R3 FootprintSoldering KitSolderable-Like BreadboardBlueSMiRF or Comparable 6-pin PinsDetachable Test Area

DescriptionOne ruler to rule them all. This is a basic 12 inch ruler， but made from a PCB. We have included a lots of useful information on each side of the ruler that you might use on a daily basis including Wire Gauge holes， transistor diagrams， common fractions， Roman numerals， and metric to imperial conversions. Most importantly， the ruler provides you with a straight line and centimeter markings one side and inch markings on the other side.You'll also find a small protractor in the middle for all your angle measurement needs. While we figured you have a fairly good idea how to use a ruler we do have a tutorial to explain all the information you'll see!Get Started with the How to use a Ruler GuideFeatures12 inch PCB ruler with markings down to 0.05" or 1/32"30.48 cm PCB ruler with markings down to 0.1mmElectrical Equations such as Ohm's Law and Parallel ResistorsKeyboard Alt CodesColor WavelengthsProtractorMetric Prefix Summary ChartMetric conversionsMorse CodeTransistor DiagramsRoman NumeralsFraction SummaryWire Guage ChartTap and Drill ChartSize：12"x 1.5"

DescriptionIt's time to say hip hip array for this IR Breakout! The MLX90640 SparkFun IR Array Breakout is equipped with a 32x24 array of thermopile sensors creating， in essence， a low resolution thermal imaging camera. With this breakout you can detect surface temperatures from many feet away with an accuracy of ±1.5℃(best case). To make it even easier to get your infrared image， all communication is enacted exclusively via I2C， utilizing our handy Qwiic system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.This specific IR Array Breakout features a55°x35°field of view with a temperature measurement range of -40℃-300℃. The MLX90640 IR Array has pull up resistors attached to the I2C bus； both can be removed by cutting the traces on the corresponding jumpers on the back of the board. Please be aware that the MLX90640 requires complex calculations by the host platform so a regular Arduino Uno(or equivalent)doesn't have enough RAM or flash to complete the complex computations required to turn the raw pixel data into temperature data. You will need a microcontroller with 20，000 bytes or more of RAM. To achieve this， we recommend a Teensy 3.1 or above.The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.Get Started with the SparkFun IR Array Breakout GuideFeaturesOperating Voltage：3V-3.6VCurrent Consumption：～18mAField of View：55°x35°Measurement Range：-40℃-300℃Resolution：±1.5℃Refresh Rate：0.5Hz-64HzI2C Address：0x332x Qwiic Connection Ports

DescriptionThe SparkFun MicroMod Environmental Function Board adds additional sensing options to the MicroMod Processor Boards. This Function Board includes three sensors to monitor air quality(SGP40)， humidity temperature(SHTC3)， and CO2 concentrations(STC31)in your indoor environment. To make it even easier to use， all communication is over the MicroMod's I2C bus!The SGP40 measures the quality of the air in your room or house. The SGP40 uses a metal oxide(MOx)sensor with a temperature controlled micro hotplate and provides a humidity-compensated volatile organic compound(VOC)based indoor air quality signal. Both the sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift and device to device variation.The SHTC3 is a highly accurate digital humidity and temperature sensor. The SHTC3 uses a capacitive humidity sensor with a relative humidity measurement range of 0 to 100% RH and bandgap temperature sensor with a temperature measurement range of -40℃ to 125℃. The SHTC3 builds on the success of their SHTC1 sensor with higher accuracy(±2% RH， ±0.2℃)than its predecessor， enabling greater flexibility.The STC31 measures CO2 concentrations based on thermal conductivity and has two CO2 measurement ranges：0 to 25 vol%； and 0 to 100 vol%. The measurement repeatability is 0.2 vol%， with a stability of 0.025 vol% / ℃. The measurement accuracy depends on the measurement range：0.5 vol% + 3% measured value； 1 vol% + 3% measured value. Using measurements from the SHTC3， the STC31 is able to provide humidity-compensated measurements together with improved temperature compensation. The STC31 can compensate for atmospheric pressure too - which is handy if， like us， you're up in the mountains!The outstanding performance of these three sensors is based on Sensirion's patented CMOSens(R)technology， which combines the sensor element， signal processing， and digital calibration on a small CMOS chip. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.Utilizing our handy M.2 MicroMod connector， no soldering is required to connect it to your system. Simply match up the key on your processor and function board's beveled edge connector to their respective key on the M.2 connector， then secure them to the main board with screws. The MicroMod Environmental Function Board can then be read via the I2C port. The board is equipped with the AP2112 3.3V voltage regulator， I2C pull-up resistors， power LED， jumper to disable the LED， and jumpers for alternative STC31 addresses.Note：A MicroMod Processor and Main Board are not included with this MicroMod Environmental Function Board. These boards will need to be purchased separately.MicroMod is a modular interface ecosystem that connects a microcontroller "processor board" to various "carrier board" peripherals. Utilizing the M.2 standard， the MicroMod standard is designed to easily swap out processors and function boards on the fly.

DescriptionSometimes we want our projects on， but sometimes we want to turn them off for a while to save power. The SparkFun Nano Power Timer will run while only consuming minimal power(approximately 35nA)and turn your project on after a set amount of time. When you are done polling your sensors， posting data to the web， writing to your logger， or planning world domination， your microcontroller can tell the Nano Power Timer to turn off the power. No more running your microcontroller all day when you only want to read the ambient temperature once per hour.The TPL5110 delay is configured with the use of resistors. We've added a six-way DIP switch to select one of the five preinstalled resistors. The sixth switch is attached to a pad to add your own PTH(or SMD)resistor. The delays associated with the preinstalled headers are shown on the bottom of the board for quick setup. Additionally， you can select more than one switch to combine the resistors in parallel(up to 26 options not including the custom resistor)， check out the hookup guide for a nice chart as to the total resistance and corresponding delay for each combination.The Nano Power Timer can handle voltages between 1.8V and 5.5V as well as current up to 1.1A with times from 100ms to two hours(preconfigured settings range from 30s to 2h). You will find a button on the board which will allow you a quick override to the delay so you can turn your project on whenever you like.Get Started with the SparkFun Nano Power SwitchFeaturesSupply Voltage：1.8V to 5.5VCurrent consumption at 2.5V：35nA Typical(50nA Max)Selectable Time intervals：100ms to 7200s(2 hours)Timer Accuracy：1%

DescriptionThis is the FemtoBuck， a small-size single-output constant current LED driver. Each FemtoBuck has the capability to dim a single high-power channel of LEDs from 0-350mA at up to 36V while the dimming control can be either accessed via PWM or analog signal from 0-2.5V. This board is based off of the PicoBuck LED Driver， developed in collaboration with Ethan Zonca， except instead of blending three different LEDs on three different channels the FemtoBuck controls just one.For the FemtoBuck， we've increased the voltage ratings on the parts to allow the input voltage to cover the full 36V range of the AL8805 driver. Since the FemtoBuck is a constant current driver， the current drawn from the supply will drop as supply voltage rises. In general， efficiency of the FemtoBuck is around 95%， depending on the input voltage. On board each FemtoBuck you will find two inputs for both power input and dimming control pins and an area to install a 3.5mm screw terminal. Finally at either side of the board you will find small indents or "ears" which will allow you to use a zip tie to secure the wires to the board after soldering them down. This version of the FemtoBuck is equipped with a small solder jumper that can be closed with a glob of solder to double the output current from 330mA to 660mA.

DescriptionThis is the SparkFun RFM69 Breakout， a small piece of tech that breaks out all the pins available on the RFM69HCW module as well as making the transceiver easy to use. The RFM69HCW is an inexpensive and versatile radio module that operates in the unlicensed ISM(Industry， Science and Medicine)radio band. It's perfect for building inexpensive short-range wireless networks of sensors and actuators for home automation， citizen science and more.This RFM69HCW operates on the 434MHz frequency and is capable of transmitting at up to 100mW and up to 300kbps， but you can change both of those values to fit your application. For example， you can maximize range by increasing the transmit power and reducing the data rate， or you can reduce both for short-range sensor networks that sip battery power. At full power and with simple wire antennas， we can get messages from one side of a large office building to the other through numerous internal walls. In open air you can reach 500 meters or more. With more complex antennas and modulation schemes， similar parts have successfully transmitted from space to the ground(by very smart amateur radio enthusiasts； your mileage may vary)!The RFM69HCW uses an SPI(Serial Peripheral Interface)to communicate with a host microcontroller， and several good Arduino libraries are available. It supports up to 256 networks of 255 nodes per network， features AES encryption to keep your data private， and transmits data packets up to 66 bytes long.SparkFun sells two versions of the RFM69HCW：a 915MHz version and this 434MHz version. Although the ISM band is license-free， the band itself is different in different areas. Very roughly， 915MHz is for use in the Americas， and the 434MHz version is for use in Europe， Asia and Africa. Check your local regulations for other areas.Get Started with the RFM69HCW Hookup GuideFeaturesTransmit power：-18dBm(0.016mW)to +20dBm(100mW)in 1dBm stepsReceive sensitivity：down to -120dBm at 1.2kbpsModulation types：FSK GFSK MSK GMSK OOKBit rates(FSK)：1.2kbps to 300kbpsVoltage range：1.8V to 3.6VCurrent consumption：0.1uA sleep， 1.25mA standby， 16mA receive， 130mA transmit(max)Encryption：AES 128-bit(optional)Packet buffer(FIFO)：66 bytes0.8"×1.1"

DescriptionThis 2x20 pin female header is meant to allow you to extend the reach of any board with the standard 2x20 GPIO pin footprint like the Raspberry Pi， Google Coral， and NVIDIA Jetson. You can also solder it to Pi HATs that do not have headers on the board. This is assuming that the board is only populated on the top of the board or the height of the components do not get in the way if it is a two layer board.The pin header is 16mm in height and the pin length is 7.30mm. This header also has standard 0.1" spacing.Note：Please note that this product is just the header. The Raspberry Pi， enclosure， Pi Wedge， and breadboard are sold separately.
