The 16 relay module and the Raspberry Pi: not an ideal marriage – Arduino, ESP8266, ESP32 & Raspberry Pi stuff

If you need lots of Relays to switch, the 16 channel relay board(above) that is available at various Chinese webshops seems like a good idea, and in fact it is if you use 5Volt logic. It is a complete different matter if you like to use it with a 3v3 system such as the raspberry…
