- Whats the purpose of the bidirectional TVS on GPIO13, 14 15? Since the gate driving circuitry is on the PCB, I don't see what is being protected here. It is also bi-directional, you'd typically use unidirectional. Wouldn't it be more benefit on the other side of the FET?
- Do you have enough heatsinking to handle 10A, it looks like with those FETs it will be over 5W per device.
- If you are clipping POT and GPIO0, then the 3v3 rail may need some clamping.
- Is gpio0 serial?
- this thread could go in the project section.
