Does not work
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

Need to add a jumper for each channel
I like this robust 2 channel relay with NO and NC connectors.All the connections are well marked in both English and Chinese. You have to add a jumper (not supplied) to the jumper pins alongside the 5Volt power supply connectors. See the picture: this yellow yumper activates the Hi voltage (2.5 to 5V) range to the trigger on the second relay.. So: for a 5v trigger you need to short between the COMmon pin and the Hi pin for each of the relays that you want to use. For a below 2.5V trigger you need to place a jumper between the COMmon pin and the LOW pin for each of the relays. You can use a low trigger on one relay and a high trigger on the other relay. But obviously you use either Low or High for each relay, not both!

Tutto ok

does not work. tried everything. GND to input, 3,3V to input, 5V to input 1. white led lights up/fashes shortly but not relay switching. input 2 is working. unit faulty. bot other relais from other store and these work fine.

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

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

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.
