SERVOGRBL Breakout board for ESP32 DEVKITC (NodeMCU ESP32)

[Doddy]

Please do me a favour and design your hardware to behave in a robust and dependable manner within the environment that you're advertising it. Don't think for a second that a RC filter will protect against spurious noise/triggers on sensor inputs; support 12-24V signalling; provide high current open drain drives for similar. Galvanic isolation where appropriate.

My point?, and my frustration is centred around many instances of people chasing problems with electronics that are not fit for purpose in a semi-industrial environment.

I've no problem with the use of microcontrollers here (some here do) and the ESP32 is a useful device compared to the AT Megas, but please research the real world problems people encounter with control systems with similar designs to those you link to,
