Description。The SparkFun Multiplexer Breakout provides access to all pins and features of the 74HC4051， an 8-channel analog multiplexer/demultiplexer. The 74HC4051 allows you to turn four I/O pins into eight multifunctional， individually selectable signals， which can be used to do everything from driving eight LEDs to monitoring eight potentiometers.。The 74HC4051 can function as either a multiplexer or a demultiplexer， and it features eight channels of selectable inputs/outputs. The routing of common signal to independent I/O is set by digitally controlling three select lines， which can be set either high or low into one of eight binary combinations.。One half of the board breaks out the control signals(E， S0-S2)and common input/output(Z). The other side provides access to all eight independent I/O's(Y0-Y7). Both sides include supply and ground connections(VCC， VEE， GND).。Get Started with the 74HC4051 Breakout Guide。Features。Switches analog or digital signals。8 channels controlled by 3 select inputs。Wide voltage supply range：2 -- 10V。Bipolar supply support(e.g.， ±5V)。Optional enable input。Breadboard compatible breakout

Description。Robots are fun， and Arduinos are easy. So wouldn't it be nice if there were kit that included everything you need to get your Arduino device set up to control simple two-motor-circuit buddy? The SparkFun Ardumoto Shield Kit is perfect for any robot enthusiast and includes an Ardumoto Shield， as well as pairs of tires， motors， connectors and wires. And， of course， it's all stuffed in classic SparkFun red box(which may come in handy as robot chassis).。The Ardumoto Shield is an easy-to-use dual-motor controller for Arduino. Combined with an Arduino， the Ardumoto makes fantastic controller platform for RC vehicles or even small autonomous robots. At the heart of the Ardumoto --- the big， black chip right in the middle --- is an L298， one of our favorite dual-channel motor drivers around， capable of driving up to 2A per channel. The board takes its power from the same Vin line as the Arduino board and includes blue and yellow LEDs to indicate active direction. All driver lines are diode protected from back EMF.。Note：The motors included with this kit are not compatible with the Wheel Encoder kit. Sorry for the inconvenience.。Get Started with the SparkFun Ardumoto Kit Guide

Description。The SCD30 from Sensirion is a high quality Nondispersive Infrared(NDIR)based CO2 sensor capable of detecting 400 to 10000ppm with an accuracy of ±(30ppm+3%). In order to improve accuracy the SCD30 has temperature and humidity sensing built-in， as well as commands to set the current altitude. For additional accuracy the SCD30 also accepts ambient pressure readings!。We've written an Arduino library to make reading the CO2， humidity， and temperature very easy. It can be downloaded through the Arduino Library manager：search for 'SparkFun SCD30' or it can be found in the。Documents。tab above.。The SCD30 Humidity and Temperature Sensor can also be automatically detected， scanned， configured， and logged using the OpenLog Artemis datalogger system. No programming， soldering， or setup required!。Note：The SCD30 has an automatic self-calibration routine. Sensirion recommends 7 days of continuous readings with at least 1 hour a day of 'fresh air' for self-calibration to complete.。Features。Power supply voltage：3.3V - 5.5V。NDIR CO2 sensor technology。Integrated temperature and humidity sensor。Best performance-to-price ratio。Dual-channel detection for superior stability。Small form factor：35 mm×23 mm×7 mm。Measurement range：400 ppm - 10.000 ppm。Accuracy：±(30 ppm + 3%)。Current consumption：19 mA @ 1 meas. per 2 s.。Energy consumption：120 mJ @ 1 measurement。Fully calibrated and linearized。Digital interface UART or I2C
