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.

DescriptionThe SparkFun Qwiic LED Stick features ten addressable APA102 LEDs， making it easy to add full color LED control using I2C. Write to individual LEDs to display a count in binary， or write to the whole strip for cool lighting effects. You can even add more LEDs to the end if you need to. We've written an Arduino library and Python package that take care of the I2C and communication to the LEDs so all you have to do is decide what color each LED should be.The LED Stick has a default I2C address of 0x23 but can be changed with a simple command， allowing you to control up to 100 LEDs(10 Qwiic LED Sticks)on a single bus! The address can also be changed to 0x22 by closing the solder jumper on the back of the board.This board is one of our many Qwiic compatible boards! Simply plug and go. No soldering， no figuring out which is SDA or SCL， and no voltage regulation or translation required!Warning：Using a lot of LEDs can draw a lot of current. Make sure to consider the power limits of your setup. If you expect your LED chain to draw more than 600mA of current， connect your external supply directly to VLED. Closing the jumper from VLED to VCC will add a 4.7uF decoupling capacitor.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 module allows a designer to leverage the Raspberry Pi hardware and software stack in their own custom systems and form factors. In addition this module has extra IO interfaces over and above what is available on the Raspberry Pi model A/B boards， opening up more options for the designer.This is all integrated onto a small(67.6mm×31mm)board that fits into a standard DDR2 SODIMM connector. You get the full flexibility of the BCM2837 SoC(which means that many more GPIOs and interfaces are available than with a standard Raspberry Pi)， and designing the Module into a custom system should be relatively straightforward because all the tricky bits have been put onto the Module itself.The CM3+ Lite product is the same as CM3+ except the eMMC Flash is not fitted， and the SD/eMMC interface pins are available for the user to connect their own SD/eMMC device. Note that the CM3+ is electrically identical and， with the exception of higher CPU z-height， physically identical to the legacy CM3 products.Note：The CM3+ modules require a software/firmware image dated November 2018 or newer to function correctly.FeaturesBroadcom BCM2837B0， Cortex-A53(ARMv8)64-bit SoC @ 1.2GHz1GB LPDDR2 SDRAMOperating Supply Voltage：1.8V， 3.3VMinimum Operating Temperature：-25CMaximum Operating Temperature：+80CHDMI， MIPI， USB， and GPIO interfaces on edge connector

DescriptionThe SparkFun MAX31855K Thermocouple Breakout is a simple 14-bit resolution， SPI-compatible， serial interface thermocouple digitizer that makes reading a wide range of temperatures possible. A thermocouple works by taking two wires made of dissimilar metals， connecting them at the two ends， and making a temperature gradient between one end and the other(a 'hot' end and a 'cold' one). Once this is achieved， a voltage potential is formed and current flows. The SparkFun Thermocouple Breakout takes a standard Type-K thermocouple in one end， digitizes the temperature measured and sends that data out the other end via a SPI interface， thereby interpreting the data and translating it for you to read!With the SparkFun Thermocouple Breakout， the thermocouple's hot junction can be read from -200℃ to +700℃ with an accuracy of ±2℃ while the cold junction， inside the MAX31855K， can only range from -20℃ to +85℃ while maintaining ±2℃ accuracy. The MAX31855K constantly measures the temperature of the cold junction using an internal temperature-sensing diode. The MAX31855K requires a power source from +3.0V to +3.6V(+3.0V nominal)and only draws 1.5mA maximum.The Thermocouple Breakout is designed to accept a standard thermocouple connector， for convenience and compatibility with probes you may already own. These connectors aren't necessary， and you could solder a thermocouple directly into the through-holes labeled '+' and '-'. If you decide to solder the thermocouple directly to the breakout board， it is recommended that the thermocouple be mounted for strain relief to avoid breaking the thin wires. Notches for a zip-tie or wire wrapping have been provided in the PCB opposite the header for this purpose.Features14-bit ResolutionSPI-Compatible， Serial Interface-200℃ to +700℃ Temperature Reading with ±2℃ Accuracy3.0V to 3.6V(+3.0V nominal)RequiredAccepts Type-K Thermocouple

DescriptionThe SparkFun Qwiic MicroPressure Sensor is a miniature breakout equipped with Honeywell's 25psi piezoresistive silicon pressure sensor. This MicroPressure Sensor offers a calibrated and compensated pressure sensing range of 60mbar to 2.5bar， easy to read 24 bit digital I2C output， and can be calibrated and compensated over a specific temperature range for sensor offset， sensitivity， temperature effects， and non-linearity using an on-board Application Specific Integrated Circuit(ASIC). With its ultra-low power consumption and Qwiic ports， you've got yourself a power packed little sensor!Each Qwiic MicroPressure Sensor has a calibrated pressure sensing range from 1-25psi and a power consumption rate as low as 0.01mW typ. average power， 1Hz measurement frequency for ultimate portability. Used in multiple medical(blood pressure monitoring， negative pressure wound therapy)， industrial(air braking systems， gas and water meters)， and consumer uses(coffee machines， humidifiers， air beds， washing machines， dishwashers)， the SparkFun Qwiic MicroPressure Sensor is a great addition to the SparkFun Qwiic ecosystem!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 Qwiic MicroPressure Hookup GuideFeaturesPressure Type：AbsoluteOperating Pressure：25psi(172.37kPa)I2C Address：0x18Accuracy：±0.25%Voltage - Supply：1.8V-3.6VPort Size：Male - 0.1"(2.5mm)TubePort Style：BarblessMaximum Pressure：60psi(413.69kPa)Compatible with a variety of liquid media2x Qwiic Connectors

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.

A multiplexer/Mux is required to communicate to multiple SHTC3 sensors on a single bus. The SHTC3 uses the same address as the Qwiic Mux(0x70). For advanced users that are using multiple SHTC3's with the Qwiic Mux， you will need to adjust the Qwiic Mux's default address.
