Microchip ATmega32U4 based development board, known under number of various names as Teensy, Leaonardo, Arduino Mico and Adafruit ATmega32U4 breakout boards to name the few.

All pins from the processor are routed out to the headers including user and communication LED's  for anyone that would re-write board library where needs those pins for their project or just like to wire those pins somewhere else in their project.

Labels on top of the board are of actual port labels and markings on bottom of the board are those of Arduino Leonardo.
