Yes, you would send position or speed values to each channel. There should be an example in the documents. If I misunderstand let me know and I will research further. Arduino IDE, no problem, and I’m sure it is facilitated in UIFlow.

@crami25 Thanks for the comprehensive reply. It really helps to deepen my understanding. As you pointed out, I always check the M5 Unit's schematic first to assure the protective resistors when I connect the Units to an ESP developing board.
