raspberry pi EP-0099 4 channel relay module schematic - RustyOx - 30-06-2022 I bought this for my home automation project, it is planned to be used to control siren and flashlight for my security system. Board was bought from Amazon. I noticed that the NC, NO is labelled wrong. The NC pin on board is actually normal open (NO). It doesn't fit well on my Raspberry Pi 4 case, after cut some bits and drill a few holes ( for heat dissipation purpose), I have managed to put it in the Raspberry Pi case.
