Controlling Relay with M5 Tough using 24VDC Supply



  • When I'm running certain GPIO pins by adding a 24V supply and driving a transistor (TIP41C) to activate the relay, it works fine as long as the relay doesn't drive any power. However, the moment the normally open (NO) contact of the relay drives power, after some time, the touchscreen of M5Tough stops working, and the screen displays fully black.
