3.3V Buck ESC Board

This was designed as a external buck conveter board to supply the suction fan motor for my Micromouse robot. The board also built-in a lower side Mosfet driver along with 2 parrel N channel mosfet. This all in one board can drive a 1 cell DC motor by only conncet VCC, GND and a PWM pin to the main board to maintain the maximal flexibilty for my Micromouse design.
