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%

DescriptionThe Raspberry Pi Compute Module 3+ Lite contains the guts of a Raspberry Pi 3 Model B+(the BCM2837 processor and 1GB LPDDR2 RAM). 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

DescriptionPoke Home Connectors have been featured on a number of our boards over the last few years by providing a simple screw-terminal-type connector for easy wire connection purposes. Similar to screw terminals， Poke Home Connectors grasp a wire entered into the receiving area of the pin-out by pressing down on the small plastic strip at the end of the housing. Doing so raises the internal clamp and， upon release of the button secures the wire in place without any soldering required.Poke Home Connectors work better in environments with a lot of vibrations(i.e. automotive applications)or when a wire is expanding or contracting due to temperature cycling. Additionally， the tension in the connector is automatically adjusted to the wire gauge(assuming it is within the accepted wire thickness)as opposed to variances in tension when a user tightens the screw terminal.

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.

DescriptionWe all like to know the temperature， right? Well， with the SparkFun TMP102 Digital Temperature Sensor， we've made it just about as easy as it gets. Based on the original Digital Temperature Sensor Breakout TMP102， we've added Qwiic connectors to bring this board into our plug-and-play Qwiic Ecosystem and added an address jumper instead of breaking out the address pin. However， we still have broken out 0.1"-spaced pins in case you prefer to use breadboard.The TMP102 itself is an easy-to-use digital temperature sensor from Texas Instruments. While some temperature sensors use an analog voltage to represent the temperature， the TMP102 uses the I2C bus of the Arduino to communicate the temperature.The TMP102 is capable of reading temperatures to resolution of 0.0625℃， and is accurate up to 0.5℃. The breakout has built-in 4.7kΩ pull-up resistors for I2C communications and runs from 1.4V to 3.6V. I2C communication uses an open drain signaling， so there is no need to use level shifting.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 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 Qwiic TMP102 Digital Temperature Sensor GuideFeaturesUses the I2C interfaceI2C Address：0x48 by default(Three additional addresses available， as well)12-bit， 0.0625℃ resolutionTypical temperature accuracy of ±0.5℃3.3V sensorSupports up to four TMP102 sensors on the I2C bus at time2x Qwiic Connectors

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 SparkFun Line Follower Array is a long board consisting of eight IR sensors that have been configured to read as digital bits! We have designed the SparkFun Line Follower Arrays to follow a dark line of about 3/4 inch width or smaller(spray paint or electrical tape)on a light background. Each array features visible LEDs that point upward when the board is attached(properly)so you can see what the robot sees， brightness control right on the board， and an I2C interface for reading and power control. Here at SparkFun， the RedBot Shadow Chassis was used as a test platform but really this was designed as an add-on for almost any bot.The line follower functions by taking an 8-bit reading of reflectance for use with following lines or reading dark/light patterns and can see from about 1/4 to 3/4 inches away. The IR brightness control and indicator can be adjusted with the on-board potentiometer and is capable of showing you the strength of the IR LEDs. Illumination can be turned on and off with software to conserve power， or left on all the time for faster readings. The SparkFun Line Follower Array requires 5V of power with a supply current range of 25-185mA with strobing disabled and 16-160mA with it enabled. Additionally we have added six mounting holes to the line follower with the two inner holes designed to fit our Shadow Chassis while the other four are general purpose.Note：As you know our Sun emits quite a bit of infrared light， making the SparkFun Line Follower Array much less effective in direct sunlight. Plan your projects accordingly!Features8 sensor eyes(QRE1113， like in our line sensor breakout)I2C interfaceAdjust IR brightness on the fly with a knobSwitch IR on and off with softwareSwitch visual indicators on and off with softwareInvert dark/light sight with softwareBased on the SX1509 I/O expander

DescriptionThis straight bar load cell(sometimes called a strain gauge)can translate up to 5kg of pressure(force)into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to， and proportional of， the strain(e.g. pressure or force)applied to the bar. With this gauge you will be able to tell just how heavy an object is， if an object's weight changes over time， or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.Each straight bar load cell is made from an aluminum-alloy and is capable of reading a capacity of 5kg. These load cells have four strain gauges that are hooked up in a wheatstone bridge formation. The color code on the wiring is as follows：red = Exc+， green = Sig+， black = Exc-， and white = Sig-.

With this gauge you will be able to tell just how heavy an object is， if an object's weight changes over time， or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.Each straight bar load cell is made from an aluminum-alloy and is capable of reading a capacity of 100g. These load cells have four strain gauges that are hooked up in a wheatstone bridge formation. The color code on the wiring is as follows：red = Exc+， green = Sig+， black = Exc-， and white = Sig-. Additionally， these load cells offer an IP65 protection rating and features four M3 sized through-holes for mounting purposes.Get Started with the Load Cell GuideFeaturesCapacity：100gMaterial：Aluminum-AlloyParallel Beam TypeIP65 Rating47mm×12mm×6mm， 110mm Wire

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.
