Thanks for the reply, I am trying to use this card with Arduino Cloud and invest the KC868-A4 model I managed to activate the releases as per the demo scheme:
Const Int relay1 = 2;
Const int Relay2 = 15;
Const int Relay3 = 5;
Const int Relay4 = 4;
In the KC868-A4S card the scheme is different and I don't understand how to activate the releases. Thank you
