Pro Micro Atmega32u4 is an Arduino compatible, very small and powerful micro controller development board. The integrated USB transceiver makes an additional USB-TTL bridge IC obsolete. Together with the micro USB port, Pro Micro Atmega32u4 is only 4 mm high. With dimensions of 34 x 18 mm is Pro Micro Atmega32u4 only 3/4 of the size of an Arduino Nano, and only the half of its height.

The tiny little Pro Micro Atmega32u4 board does all of the Arduino tricks that youre familiar with:

9 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite Arduino-compatible boards but this little guy can go just about anywhere.

There is a voltage regulator on board which can accept a power supply of 6-9VDC (max. 10V).Make sure to connect the input voltage to the RAW pin and not VCC (5V).

The Pro Micro Arduino compatible board is originally developed as open hardware by the company Sparkfun. It comes with the Atmel Atmega32u4 MCU and runs with 16MHz. A pair of pin headers is included, as shown on the picture.

  • ATmega32U4 running at 5V/16MHz
  • Supported under Arduino IDE v1.0.1 and above
  • On-Board micro-USB connector for programming
  • 9 x 10-bit ADC pins
  • 12 x Digital I/Os (5 are PWM capable)
  • Rx and Tx Hardware Serial Connections
