The Arduino Pro Micro Atmega32u4 is a small, breadboard-friendly microcontroller board. It has an operating voltage of 5V and a clock speed of 16 MHz, making it suitable for a wide range of applications. The ATmega32U4 microcontroller has 32KB of flash memory, 2.5KB of SRAM, and 1KB of EEPROM, and features built-in USB support, which eliminates the need for a separate USB-to-serial converter. The Arduino Pro Micro has several digital and analog input/output pins, making it easy to interface with sensors, actuators, and other components. It is commonly used for DIY electronics projects, hobbyist inventions, and educational purposes, and is ideal for projects that require a compact and low-cost microcontroller board.

9 channels of 10-bit ADC, 5 PWM pins, 12 digital I/O as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorited, 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 are included, as shown in 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
  • Dimensions: 34 x 18mm

    m.p (verified owner)

    This is a Pro Micro clone, built with the same 32u4 chip that’s in the original (and the Leonardo, among a couple of others). The beauty of the 32u4 is that it has USB built into it in such a way that in addition to serial communication and programming, you can get it to act like a keyboard or mouse (there are Arduino libraries to do this).

    Worked right out of the package, pins soldered on nice and clean, and the LEDs are bright. I’m currently using it to read when a switch is closed and then act like a mouse to do a whole bunch of left-clicks to gather stuff in a game I play.

    I bought this when it was $7.75 which is a pretty good price, especially considering that it only took a few days to get here. I see it’s $6.90 now, which is a great price!
