I couldn't get it to work with my Arduino and an external 5V power supply. Tried it with my lab power supply. I discovered the relays don't get triggered at 5.0V. But at about 5.6V they do, but I can't turn up my 5V supply that far. Then you have to put jumpers on the high or the low trigger pins, but those are not supplied. Useless rubbish.

La carte fonctionne en 12v et non en 5v comme indiqué, donc inutilisable avec notre carte de commande.

La commande ne fonctionne pas en 5V. J'ai dû pousser à 9V pour que cela déclenche les relais.

No instructions of any kind. Found what others had said to work out jumpers - BUT it does not work. It does not function with Arduino, despite what the description says. When the jumper for S1 or S2 is set COM to LOW, there is ~4V on the input, and the Arduino cannot sink or source the current to overcome this voltage and bring it down to 0. I tried shorting the S1 input to ground - which should turn the relay on, but it does not. The LED for S1 flashes briefly brightly then goes dim - looks like a fault unit
