Description。The 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.

Description。The 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.

Description。The SparkFun ZOE-M8Q GPS Breakout is a high accuracy， miniaturized， GPS board that is perfect for applications that don't possess a lot of space. The on-board ZOE-M8Q is a 72-channel GNSS receiver， meaning it can receive signals from the GPS， GLONASS， BeiDou， and Galileo constellations. This increases precision and decreases lock time and thanks to the onboard rechargable 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 made 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.。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 ZOE-M8Q：baud rates， update rates， geofencing， spoofing detection， external interrupts， SBAS/D-GPS， etc. All of this can be done within the SparkFun Arduino Library. We've also made sure to configure the UART pin grouping on the breakout to an industry standard to insure that it easily connects to a Serial Basic.。The SparkFun ZOE-M8Q GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the ZOE-M8Q. This reduces the time-to-first fix from a cold start(～30s)to a hot start(～1s). The battery will maintain RTC and GNSS orbit data without being connected to power for up to five hours. Since the ZOE-M8Q is a tiny GPS receiver and to minimize its footprint， we've added a U.FL connector to allow the use of both large standard ceramic antennas as well as very small chip scale antennas.。Note：The I2C address of the ZOE-M8Q is 0x42 and is software configurable. A multiplexer/Mux is required to communicate to multiple ZOE-M8Q sensors on a single bus. If you need to use more than one ZOE-M8Q 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. 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.。The ZOE-M8Q GPS Breakout can also be automatically detected， scanned， configured， and logged using the OpenLog Artemis datalogger system.

。Description。USB 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.

Description。The SparkFun TSH82 Configurable OpAmp Board was designed to give you the best combination of performance and flexibility that we could achieve by giving you two gain stages， each one independently accessible on the header pins. Each stage is natively configured as an inverting amplifier that can also be strung together to expand the capabilities of the TSH82 from STMicroelectronics. With the use of the jumpers on the back of the board， you can configure each stage for non-inverting operation， differential input， and DC input coupling.。Electrically speaking， both stages on this board are identical. The default configuration is inverting with a gain of -4.7 with a bandwidth of almost 10MHz. Input signals are AC coupled， possess an input impedance of 10K with a low frequency cutoff of 15.9Hz. Outputs are also DC coupled， so don't forget to add a capacitor to the output if you're running a single-ended supply and need to strip out the DC component. The board will also operate with a single-ended DC power supply of 4.5V to 12V， or a bipolar supply from +/-2.25V to +/-6V.。On the back of the board you'll find 10 solder jumpers that can be used to change the board's performance， but nothing there needs to be changed to use it in it's default state.。Get Started With the Configurable OpAmp Board Guide

Description。The 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.
