Description
The Pro Micro is similar to the Pro Mini, except it uses the ATMega32U4. Additionally, the 32U4 includes an on-board USB transceiver, eliminating the need for a bulky external USB interface. There is also a voltage regulator on board, which means it can accept up to 12V DC. Please bear in mind that if supplying unregulated power, you need to connect to “RAW”, not “VCC”.
Dimensions: 1.3 x 0.7″
Features:
- ATMega 32U4 running at 5V/16MHz
- Supported under Arduino IDE v1.0.1
- On-Board micro-USB connector for programming
