12V PWM power driver for Wemos D1 Mini. Uses a TC4420CPA MOSFET driver. Can power the Wemos through the 5V pin if you populate the 7805 and a couple of capacitors. If you use a 3.3V voltage regulator instead of a 7805 you can power the Wemos through the 3V3 pin. The PWM pin is D1, but the trace can be easily be cut and patched to a different pin if needed.
