ESP8266 Community Forum

- Fri Sep 30, 2022 4:17 pm #95316 Hi!
I bought the relay board on the pic some time ago and trying to use it with a 12V power supply and an esp8266 - unfortunately without success. Wiring information is not available any more
Does anyone know how to connect the board to esp and power supply in order to get it switching?
Best regards and thanks in advance,
Otto

You will find some similarities between your relay module and the one used here. The wiring part starts from 5:37 .

Unfortunately the relay in the video is 5V. Mine is 12V...
