Pro Micro 32U4 Board 5V 16Mhz Arduino Bootloader.
This tiny little board use the same 32u4 microcontroller as the Arduino Leonardo. The 32u4 is running at 16MHz and 5V. There is a voltage regulator on board so it can accept voltage up to 12VDC. If you’re supplying unregulated power to the board, be sure to connect to the “RAW” pin on not VCC.
