I have two usb 16 pololu servo controllers.
I want to connect them together, so I will use one usb instead of two plug.
I read the manual, but I want to confirm that I am doing it right without killing the controller.
Gound pin to Gound pin
Logic Supply pin to Logic Supply pin
Serial Out pin to Serial IN pin.
Is that correct?
Why don’t you want to use two USB ports? It would give you the best results. The connections you suggest should work; you should also be able to connect serial in to serial in. One other important thing you’ll need to do is connect the reset line high on the unit that is not connected to USB since the USB controller chip (the CP2102) will otherwise not let the main microcontroller run.
