Ready to add audio to your next project? This small breakout board couples a small electret microphone with a 100x opamp to amplify the sounds of voice, door knocks, etc loud enough to be picked up by a microcontroller's Analog to Digital converter. Unit comes fully assembled as shown. Works from 2.7V up to 5.5V. Links: Example Audio LED control project by Adam Greig

The HTU31-D is the third generation of temperature-humidity sensors from TE - and a great follow-up to the popular HTU21-D sensor. Like the HTU21, the '31 is great for sensing temperature and humidity, with excellent specifications. This I2C digital humidity sensor is an accurate and intelligent alternative to the common DHT-series sensors, at about the same price! It has a typical accuracy of ...

Crank up your robotics with powerful Adafruit DRV8871 motor driver breakout board. This motor driver has a lot of great specs that make it useful for a wide variety of mechatronics. In particular, the simple resistor-set current limiting and auto-magic PWM support make it super easy to use with just about any brushed DC motor. Check out the specs for the DRV8871: 6.5V to 45V motor power voltage ...
