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.

DescriptionThe SparkFun NEO-M9N GPS Breakout is a high quality GPS board with equally impressive configuration options including SMA. The NEO-M9N module is a 92-channel u-blox M9 engine GNSS receiver， meaning it can receive signals from the GPS， GLONASS， Galileo， and BeiDou constellations with ～1.5 meter accuracy. This breakout supports concurrent reception of four GNSS. This maximizes position accuracy in challenging conditions increasing， precision and decreases lock time； and thanks to the onboard rechargeable battery， you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally， this u-blox receiver supports I2C(u-blox calls this Display Data Channel)which makes it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system， no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.The NEO-M9N module detects jamming and spoofing events and can report them to the host， so that the system can react to such events. A SAW(Surface Acoustic Wave)filter combined with an LNA(Low Noise Amplifier)in the RF path is integrated into the NEO-M9N module which allows normal operation even under strong RF interferences.U-blox based GPS products are configurable using the popular， but dense， windows program called u-center. Plenty of different functions can be configured on the NEO-M9N：baud rates， update rates， geofencing， spoofing detection， external interrupts， SBAS/D-GPS， etc. All of this can be done within the SparkFun Arduino Library!The SparkFun NEO-M9N GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the NEO-M9N. This reduces the time-to-first fix from a cold start(～24s)to a hot start(～2s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time.This product requires an antenna：Be sure to check out the related products/hookup accessories and pick a suitable SMA antenna for your project.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 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 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.

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

DescriptionWith the SparkFun Qwiic Connect System expanding every day， we want to make sure it becomes as accessible as possible but we understand there are other systems that can compliment it out there. The Qwiic to Grove Adapter Cable allows interoperability between the SparkFun Qwiic Connect System and the I2C based Grove boards from Seeed Studio. Now you can plug Seeed Studio boards you may have onto the Qwiic bus or you can use this cable to introduce Qwiic sensors， inputs， and outputs into your Grove system.Note：The Grove system has a variety of different signal systems that use the same connector. This cableonlyworks with the I2C variety.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.FeaturesLength：100mm

DescriptionThese wireless receivers work with our 315MHz transmitters. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only receivers， they will only work communicating data one-way， you would need two pairs(of different frequencies)to act as a transmitter/receiver pair.Note：These modules are indiscriminate and will receive a fair amount of noise. Both the transmitter and receiver work at common frequencies and don't have IDs. Therefore， a method of filtering this noise and pairing transmitter and receiver will be necessary. The example code below shows such an example for basic operation. Please refer to the example code and links below for ways to accomplish a robust wireless data link.Note：These receivers are almost identical to the RF link 434MHz receiver. SparkFun does everything in our power to make sure you receive the product you requested. However， if you are concerned you may have received the incorrect product you can verify which version receiver this is by running a simple test circuit.Features315 MHz500ft range(given perfect conditions)4800bps data rate5V supply voltage

DescriptionGet with the times， already! This SparkFun Real Time Clock(RTC)Module is a Qwiic-enabled breakout board for the RV-1805 chipset. The RTC is ultra-low power(running at only about 22nA in its lowest power setting)so it can use a supercapacitor for backup power instead of a normal battery. This means you get plenty of charge and discharge cycles without any degradation to the "battery." To make it even easier to get your readings， all communication is enacted exclusively via I2C， utilizing our handy Qwiic system so no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.This RTC module's built in RV-1805 has not one， but two internal oscillators：a 32.768kHz tuning fork crystal and a low power RC based oscillator and can automatically switch between the two using the more precise crystal to correct the RC oscillator every few minutes. This feature allows the module to maintain a very accurate date and time with the worst case being +/- about three minutes over a year. The RV-1805 also has a built in trickle charger so as soon as the RTC is connected to power the it will be fully charged in under 10 minutes and has the ability to switch power to other systems allowing it to directly turn on or off a power hungry device such as a microcontroller or RF engine.There is also the option to add a battery to the board if the supercapacitor just isn't going keep your project powered long enough(keep in mind， the supercap can hypothetically make the board keep time for around 35 days)， you can solder on an external battery. That means you can let board sit with no power or connection to the outside world and the current hour/minute/second/date will be maintained.Note：The I2C address of the RV-1805 is 0x69 and is hardware defined. A multiplexer/Mux is required to communicate to multiple RV-1805 sensors on a single bus. If you need to use more than one RV-1805 sensor consider using the Qwiic Mux Breakout.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 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)

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 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.

DescriptionButtons are an easy and tactile way to interface with your project， but why would you want to deal with debouncing， polling， and wiring up pull-up resistors? The Qwiic Button with built-in green LED simplifies all of those nasty worries away into an easy to use I2C device! Utilizing our Qwiic Connect System， using the button is as simple as connecting cable and loading up some pre-written code!If you need multiple buttons for your project， fear not! Each button has configurable I2C address， so you can daisy-chain multiple buttons over Qwiic and still address each one individually. We've got an example in our Arduino library that provides super-easy way to configure your Qwiic Button to whatever I2C address you desire. You can download the library through the Arduino library manager by searching 'SparkFun Qwiic Button' or you can get the GitHub repo as .zip file and install the library from there.In addition to handling blinking and debouncing， the Qwiic Button has configurable interrupts that can be configured to activate upon button press or click. We've also taken the liberty of implementing FIFO queue onboard the Qwiic Button where it keeps an internal record of when the button was pressed. This means that code on your microcontroller need not waste valuable processing time checking the status of the button but instead can run small function whenever the button is pressed or clicked!
