Whanted something small size of Arduino proMini but with all pins fanned out to the headers and with USB connector for programming and with more memory resources.

Hence the this board based on the Microchip ATmega32U4. Known under number of various names as Teensy, Leaonardo, Arduino Mico and Adafruit ATmega32U4 breakout boards to name the few. Using standard leonardo boot loader the board will function as true Arduino Leonardo but in much smaller form factor.

As said earlier, pll 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.
