ATMEGA32U4 in 5 v / 16 MHZ
Under the support of the Arduino IDE V1.0.1
The board of directors on the micro USB interface programming
Four 10 bit ADC pin
12 digital I/O (PWM)
Rx and Tx hardware serial connection
This small board to do all in the neighbourhood of the Arduino skills: 4 channel 10 bit ADC, five PWM pin, 12 DIO and hardware serial connection Rx and Tx: are you familiar with.Run in 16 MHZ and 5 v, the committee will remind you of many other you like the Arduino compatible circuit board, but this little guy can go to any place.In the ship has a voltage regulator, so it can accept voltage up to 12 VDC.If you are the supply of unstable power supply board, must be connected to the “RAW” is not the VCC pin.This latest version correct silk, make the pin 14 is correct.We also added a PTC fuse and diode protection power supply circuit and correct RX and TX LED circuit.
