Arduino Pro Micro 5V/16MHz Atmega32U4-MU: Compact and Efficient Development Board with Micro USB Interface
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 Pro Micro 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.
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). A pair of pin headers are included (require soldering).
