The Wiki doc for the devastator chassis contains the following warning;
“Notice: Make sure the Tank is connected to the Arduino GND when using USB to power the microcontroller.”
Does this mean a separate physical ground between the chassis and the Romeo BLE GND pin needs to be established. Or is this their way of saying the power supplies (Motor and Controller) need to have a common ground. The wiring diagrams on the same Wiki doc do not show this connection. How do I achieve this connection since there is no GND screw terminal. Is this only required for USB operation and should it be removed for normal operation.
Thanks
