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.

Description。The 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.

。Description。The SparkFun Continuous Rotation(CR)Servo Trigger is a small robotics board that simplifies the control of hobby RC servo motors. When an external switch or logic signal changes state， the CR Servo Trigger is able to tell an attached servo motor to move from position A to position B. To use the CR Servo Trigger， you simply connect a hobby servo and a switch， then use the on-board potentiometers to adjust the start/stop positions and the transition time. You can use a hobby servo in your projects without having to do any programming!。When we introduced the original Servo Trigger， we mentioned that it could be reprogrammed to be more useful with continuous rotation servo motors. But reprogramming the firmware is somewhat tedious， and users asked for a Servo Trigger preprogrammed with the continuous rotation logic. With this little board you will be provided an easy way to deploy continuous rotation servos into your projects!。The heart of the CR Servo Trigger is an Atmel ATtiny84 microcontroller， running a small program that implements the servo control features designed for continuous rotation servos. On board each of these CR Servo Triggers you will find three potentiometers："A" sets the position the servo sits in while the switch is open， "B" sets the position the servo moves to when the switch is closed， and "T" sets the time it takes to get from A to B and back.。Compared with a servo motor， the CR Servo Trigger board draws very little current， roughly 5mA at 5V. Be sure to note that if you're using the CR Servo Trigger to control your motor， the absolute maximum supply voltage that should be applied is 5.5 VDC. Additionally， the SparkFun CR Servo Trigger is designed to make it easy to daisy chain boards - you can simply connect the VCC and GND pads on adjacent boards to each other.。Note：This idea originally came from our friend in the Oakland area， CTP. If you see him， please give him a high-five for us.。SparkFun CR Servo Trigger Hookup Guide。Features。Recommended Voltage：5VDC。Max Voltage：5.5VDC。Current Draw：5mA。Control Continuous Rotation Servos。Three Control Settings。A - sets the position the servo sits in while the switch is open。B - sets the position the servo moves to when the switch is closed。C - sets the time it takes to get from A to B and back。Easy Control with Potentiometers。Configurable Input Polarity。Configurable Response Mode。Compatible with Analog Servos。ISP Header Pins Available for Reprogram
