Pro Micro adopts Atmega32U4's own USB update program 5V/16M microcontroller development board

Product Descriptions:

ATMEGA32U4 operates at 5V/16MHz

Supported Arduino IDE V1.0.1

Micro USB interface programming at the board meeting

4 10 bit ADC pins

12 digit I/O (5 PWM capability)

Rx and Tx hardware serial connection

Explain:

This small board has all the neat and adjacent Ard uino techniques: 4-channel 10 bit ADC, 5 PWM pins, 12 DIO, and hardware serial connection Rx and Tx, which you are familiar with. Running at 16MHz and 5V, but this little guy can go anywhere. There is a voltage regulator on board, so it can accept voltages up to 12VDC. If you are using an unstable power board, be sure to connect it to the 'RAW' pin that is not VCC. This new version fixes the silk error, making pin 14 correctly labeled. We have also added a PTC fuse and diode to protect the power circuit and correct the RX and TX LED circuits
