I am trying to get to full robotic with control from a PC for startup to shutdown. I’m using a smart plug to switch on power to each device but the PC power is always on. I can switch off the dome power supply but the controller board stays on because of the USB.
So 1) i didn’t like the idea of the board staying on at all times due to daytime heat, but will it survive?
2) If I disconnected 5V from the Vcc bus from the PC by just cutting red line in the cable, so that the board is powered only if main supply is on, Will USB port still communicate? Or does it need Vcc+5 to the port to allow Tx/Rx.
