Used with 12v push buttons to control 240v lightning.
Really cool and so easy to use! I ordered single module to test it and ended up with this one as I wanted to control 2x under cabinet lights and 1x ceiling LED in the living room. All devices are smart but I wanted to have an option to ON/OFF them in case of Home Assistant failure. So I figured out, that the easiest and safest way will be to used 12v push buttons in the worktop and they worked really well with this device. Just needed to swap the yellow jumper to low voltage as it didn't work at the beginning. Really cool device.

Beware
Beware, this board does NOT provide optical isolation.

Worked out of the box without issues
This a great interface board. The board needs a 5v DC supply for the relay coils but are driven by drivers which can be triggered using 3,3v so ideal for IOT devices like Arduino, ESP, Rasoberry Pi etcIt can also use either logic hi or low switching by the use of jumpers on board.
