Description:

This little board does all the neat Arduino tricks you’re familiar with: a 4-channel 10-bit ADC, 5 PWM pins, 12 DIO pins, and Rx and Tx hardware serial connections. Running at 16MHz and 5V, this board will remind you of many of your favorite Arduino-compatible boards, but this little guy can go anywhere. There’s an onboard voltage regulator, so it can accept voltages up to 12VDC. If you’re using an unstable power supply, be sure to connect the “RAW” pin, not the VCC pin. This new version fixes a Silk error, so that pin 14 is correctly labeled. We also added a PTC fuse and diode to protect the power circuit and correct the RX and TX LED circuits
