I’m currently planning a robot that contains multiple MCUs (Probably Arduino’s or MicroPython Boards) and an RPI Zero and I want to have them communicate with each other. I don’t know what kind of Protocol to use. I will have multiple MCUs sending at the same time and I’m thinking of using an MCU just for managing the Communication. I really need help selecting a protocol, I was thinking about UART but I’m not sure if that’s a good idea. Please help me.
