Sounds like your components are alright. If the problem is not solved yet, I think you can share your code here. Hopefully micropython experts here will be able to figure out the issue.

Thanks a lot for the clarification again.

I know this is not what you want. But this project may give you some idea. This is a smart chessboard. This is based on ESP32-WROOM. The component list may prove helpful to you. https://www.pcbway.com/project/shareproject/Smart_Chess_Board.html That’s a great idea to have the board track the robot!...
