Shelly Plus 1 Mini

GPIO Pinout

Pin	Function
GPIO0	LED (Inverted)
GPIO1	Button (Inverted, Pull-up)
GPIO7	Relay
GPIO10	Switch input

The Shelly Plus 1 Mini is based on the ESP32-C3 (Single core, 160MHz, 4MB embedded flash) To enter bootloader mode, GPIO9 needs to be pulled down (connected to ground).

Configuration as relay
