Hello Everyone,
I searched through the site but didn't find anything on this topic. The AVR chips require very little power to operate and I have a project where the AVR remains running after the power switch is turned off. The serial port is connected to a USB to serial adapter and even though I don't have the USB 5V line attached, the AVR gets enough current from the serial line to stay on.
Is there an elegant way to keep the serial line from power the AVR? I can take a brute force approach and add a relay between the serial adapter and the AVR but it seems there should be another way.
Thanks!
