The Pro Micro is similar to the Pro Mini, except for the fact that it utilises the ATMega32U4. Additionally, there is an on-board USB transceiver inside the 32U4, which removes 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
• 4 x 10-bit ADC pins
• 12 x Digital I/Os (5 are PWM capable)
• Rx and Tx Hardware Serial Connections
Further information including support files, schematic and an example sketch is available on our support forum here.
UNFORTUNATELY, DUE TO PRICE INCREASES AND STOCK SHORTAGES IN THE INTEGRATED CIRCUITS BUSINESS, THESE BOARDS ARE NOW COSTING MORE TO MANUFACTURE. THEREFORE WE HAVE HAD TO BEGRUDGINGLY INCREASE THE PRICE.
