This tiny micro-controller board does all of the Arduino-compatible tricks that you're familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections for Rx and Tx.
Running at 16MHz and 5V, this board will remind you of your other favorite Arduino-compatible boards, but this little guy can be integrated into designs where others just won't fit, with the simplicity of an integrated Micro USB connector.
There is a voltage regulator on board so it can accept voltage up to 12VDC. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC.
