The smallest Arduino-Compatible board yet! An even smaller version of the Pro Mini, but with an ATmega32U4 (as opposed to the ATmega328 on the Pro Mini). The Pro Micro features an on board micro USB connector for instant USB connectivity that also doubles as a power supply! Ideal for small, lightweight projects that require rapid prototyping or in large volumes.

The Pro Micro (rated at 3.3V/8MHz) contains an improved ATmega32U4 chip. The 3.3V version of the Pro Micro has the advantage of ease of use with compatible 3.3V sensors combined with lower power consumption.

The Arduino compatible board includes 4 analogue pins with 10-bit ADC (Analogue Digital Conversion) for use with analogue 3.3V sensors, 5 PWM (Pulse Width Modulation) pins good for dimming LED's, 12 Digital I/O pins for general use and Rx and Tx hardware serial connections. It can even be used with the official Arduino iPhone App for further configurations.

This Pro Micro contains an on board USB transceiver, so it doesn't require any external FTDI boards to be able to connect it to a computer.

Features:

  • Smallest Arduino-Compatible board yet!
  • On-board micro-USB connector for power supply and direct programming with a computer or the Arduino IDE software iPhone app.
  • 3.3V/8MHz ATmega32U4 chip.
  • Supports auto-reset.
  • 5V regulator.
  • Max 150mA output.
  • Over current protected.
  • DC input 5V up to 12V.
  • On board Power and Status LEDs.
  • Analog Pins: 8.
  • Digital I/Os: 14.

Note:

  • The Pro Micro has an onbaord regulator that can handle up to 12VDC and regulate it down to the board's operating voltage of 3.3V. If you are doing that you need to connect the unregulated voltage to the 'Raw' pin and not the 'VCC' pin.
