DescriptionPassive Infrared(PIR)sensors are great for detecting motion in a small area around the sensor. The 170μA SparkFun EKMC4607112K PIR Breakout is a simple board equipped with an EKM-series PIR sensor from Panasonic(R). The EKM-series PIR sensors are optimized for small movements to offer motion-sensing options for continuously powered applications.PIR sensors do not return specific distance data but instead monitor for IR light coming from objects in their field of view and will activate their signal when motion is detected in their sensing area， making them perfect for applications such as turning devices on automatically when motion is detected. Applications include home and building automation for energy saving， automated on/off lighting control， security， appliances， and IoT.Panasonic's low-profile PIR motion sensors(10.9mm versus standard 14.4mm height offer space savings for constrained designs)consist of a lens to create various detection zones， an optical filter to block non-infrared light， pyroelectric sensing elements， electromagnetic shielding to all circuitry， and an impedance converter to get an electrical signal. This PIR sensor offers digital output across 32 zones at 5m detection distance with 90°×90° detection area.Note：The sensitivity of passive infrared sensors is influenced by environmental conditions， so a performance evaluation test under representative conditions is recommended.Get Started with the SparkFun PIR Breakout GuideFeaturesOperating Voltage：2.3-4.0V170 μAstandby current consumptionLens diameter - 10.4mmLens Height - 10.9mm5m detection distance90°×90°(±45°)detection area

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.

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 great thing about open source is that while SparkFun has designed our own MicroMod carrier boards， that does not stop you from creating your very own MicroMod carrier board. The MicroMod DIY Carrier Kit includes five M.2 connectors(4.2mm height)， screws， and standoffs so that you can get all the special parts you may need to make your own carrier board.MicroMod uses the common M.2 connector. This is the same connector found on modern motherboards and laptops. There are various locations for the plastic 'key' on the M.2 connector to prevent a user from inserting an incompatible device. The MicroMod standard uses the 'E' key and further modifies the M.2 standard by moving the mounting screw 4mm to the side. The 'E' key is fairly common so a user could insert a M.2 compatible Wifi module but because the screw mount doesn't align， the user would not be able to secure an incompatible device into a MicroMod carrier board.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 on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!

DescriptionIntroducing the SparkFun FT231X Breakout board， complete with the full UART hardware handshake feature! The pin-out of this board matches the FTDI cable to work with official Arduino and cloned Arduino boards. It can also be used for general serial applications.This board still brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto-reset any Arduino board that has the reset pin brought out to a 6-pin connector.The coolest thing about the FT231X Breakout is that we have broken out ALL the pins for your use， making this board all the more hackable! It also uses a common microUSB jack.One of the features of this board is a jumper on the back， which allows the VCC output to be configured to either 3.3V or 5V. This board ships default to 5V， but you can cut the default trace and add a solder jumper if you need to switch to 3.3V. It should be noted that the max input of the FT231X is only 3.3V， but it can operate down to 1.8V with external pull-ups and is also 5V tolerant.

DescriptionThe LIDAR-Lite v4 LED sensor is the next step in the LIDAR-Lite line. A small， lightweight， low-power optical ranging sensor. It's the first to incorporate ANT profile wireless networking technology into an optical sensor. Its built-in nRF52840 processor means that developers can create custom applications， or be operated as a stand-alone device right out of the box by using the preloaded stock application.Like the LIDAR-Lite v3 and LIDAR-Lite v3HP sensors； it can also be directly connected to an external micro-controller running a custom user application. As such， it provides a highly adaptable option for OEM and maker applications in robotics， Internet of Things， and unmanned vehicles ― or any application where an ultrasonic sensor might otherwise be used. It's perfect as the basic building block for applications where wireless capabilities， small size， light weight， low power consumption and high performance are important factors in a short-range， 10-meter， optical distance measuring sensor.The LIDAR-Lite v4 requires an external 5VDC power source and soldering is required. This Time-of-Flight ranging module uses a LED and optics for ranging. It does not use a laser； therefore， it is inherently eye-safe under normal usage.FeaturesResolution：1 cmMeasurement repeatability：As measured indoors to a 90% reflective target1 cm is equivalent to 1 standard deviationUsing "high accuracy" mode， with averaging：+/- 1 cm to 2 meters+/- 2 cm to 4 meters+/- 5 cm to 10 metersRange：5 cm to 10 meters(as measured from back of unit)Update rate：I2C = >200 Hz typicalANT(R)= up to 200 Hz to a 90% target indoors at 2m in normal operating modeInterface：I2C or ANT； user configurable for SPI using the Nordic SDKPower(operating voltage)：4.75 - 5.25 VDCCurrent consumption：2mA idle， 85mA during acquisitionOperating temperature：-20 to 60° CLED wavelength：940 nmBeam divergence：4.77°Optical aperture：14.9 mmUnit size(HxWxD)：2.1"×0.8"×0.9"(52.2×21.2×24.0 mm)Weight：14.6 g(0.5 oz)

DescriptionThis MI：pro Protector Case for the BBC micro：bit has been designed to work with both the original micro：bit V1 and the micro：bit V2. These cases feature a four-layer construction style with ability to mount a 2xAAA battery pack to the back of the case while still providing access to all buttons and ports on the micro：bit. Though these cases do protect the micro：bit astoundingly well， the biggest benefit of using the MI：pro is to not accidentally short out the pads on the back of the micro：bit.Construction is simple， requiring only a small flathead screwdriver(at most)， and involves layering each plate on top of one another around the micro：bit and screwing it into place. Luckily， the MI：pro Protector case enables easy access to the edge pins at the bottom of the micro：bit， allowing it to still be plugged into an edge connector found on many of our carrier boards. The only board that cannot be used in conjunction with the MI：pro case is the SparkFun gamer：bit due to its edge connector being located in the center of the board.Note：The MI：pro Protector case only includes the parts found in the Includes Tab. This case doesNOTinclude a micro：bit， power source or mounting screws. These items will need to be purchased separately.FeaturesDimensions：Length：65mm.Width：37mm.Depth(without screws)：12mm.Depth(with screws)：18.5mm.Provides excellent protection to the BBC micro：bit whilst allowing access to the bottom pins.Full access to the A and B buttons on the BBC micro：bit.Attach a battery cage to the rear of the case with the supplied sticky fixer.Full access to pins and connections including the micro USB connector.Clear case material shows the on-board LEDs in perfect clarity.The case is compatible with versions 1 and 2 of the micro：bit.When used in conjunction with a battery holder， micro：bit projects can be fully mobile.

DescriptionThe SparkFun I2S Audio Breakout board uses the MAX98357A digital to analog converter(DAC)， which converts I2S(not be confused with I2C)audio to an analog signal to drive speakers. The I2S Audio Breakout converts the digital audio signals using the I2S standard to an analog signal and amplifies the signal using a class D amplifier which can deliver up to 3.2W of power into a 4Ω load. The board can be configured to output only the left channel audio， right channel， or both.The SparkFun I2S Audio Breakout board is fairly simple， requiring only a few pin connections to get it up and working. By default the board is configured in "mono" operation， meaning the left and right signals are combined together to drive a single speaker. If you want a separate speaker for the left and right audio channels you'll need to cut the mono jumper. In addition to being able to select the audio channel output， the gain can also be configured in a few ways. The gain of the amplifier can be configured from as low as +3dB to as high as +15dB. While the channel selection can be configured on board， the gain however is controlled externally using the gain pin. By default， the board is configured for +9dB， but can be easily changed!Get Started with the SparkFun I2S Audio Breakout GuideFeaturesSupply Voltage Range：2.5V - 5.5V.Output Power：3.2W into 4Ω at 5V.Output Channel Selection：Left， Right， or Left/2 + Right/2(Default).Sample Rate：8kHz - 96kHz.Sample Resolution：16/32 bit.Quiescent Current：2.4mA.Filterless Class D OutputsNo MCLK RequiredClick and Pop ReductionShort-Circuit and Thermal Protection.

DescriptionThis small breakout board couples an Electret microphone(100Hz--10kHz)with a 60x mic preamplifier to amplify the sounds of voice， claps， door knocks or any sounds loud enough to be picked up by a microcontroller's analog-to-digital converter. Each breakout comes fully assembled and works from 2.7V up to 5.5V.The Electret Mic Breakout translates amplitude(not volume)by capturing sound waves between two conducting plates(one a vibrating diaphragm and the other fixed)in the microphone and converting them into electrical waves. These electrical signals are then amplified and picked up by your microcontroller's ADC.Get Started With the Electret Microphone Guide!

DescriptionThe SparkFun Load Sensor Combinator is a bare PCB that combines four load sensors into a standard four-wire Wheatstone bridge configuration. If you open up an electronic bathroom scale， you'll find a large rat's nest of wires. The Load Sensor Combinator was created to combine the 12 wires found in a bathroom scale into the standard four-wire Wheatstone bridge configuration.This version of the SparkFun Load Sensor Combinator features a few changes that you specifically asked for! We updated the silk on the breakout to read "C/+/-" instead of "R/W/B" and moved the temperature sensor connector away from the standoff hole.You can either use four individual load sensors or simply purchase an off-the-shelf bathroom scale and hack the combinator into it rather than trying to design a base to properly mount four load sensors.This board works great with our Load Cell Amplifier breakout board； the five pins on the edge of the combinator line up directly to the five pins on the amplifier.If your amplifier and supporting electronics are more than a few inches away from the scale， an RJ45 footprint is provided. The four Wheatstone pins(E+/E-/S+/S-)as well as the shield pin are connected to twisted pairs within a standard cheap Ethernet cable. This allows the amplifier board to be placed many feet away from the scale itself.The combinator board also includes a footprint for the DS18B20 one-wire temperature sensor. This allows the user to gather the temperature of the scale in case there is a large variance between the scale and the amplifier. These three pins are accessed through the RJ45 connection as well， allowing remote temperature readings to be gathered over one twisted pair Ethernet cable.NOTE：The SparkFun Load Sensor Combinator will only work with 3 wire load sensors， it is not compatible with 4 wire load cells.
