New board, experimental 36V/30A

First, alpha iteration of a new board Iā€™m working on to replace the one with the BTN drivers which are out of stock. This one is in stock, but have no idea if it works. One way to find out, make it and test it. This one requires 6PWM, so it would require an MCU with a lot more pins available.
