#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,
