I have no knowledge of soldering and the doorbell I believe to be wireless.
What I have is an old button board that runs on an 12v battery, with LED driver, a 10k resistor and a R433A. Says it is a 07/12/27 QH-929-1A V1 which I tried search for but could not find. Take note that I'm not experienced. I want to know what components I'm supposed to solder two wires to, as I'm looking for the doorbells terminal.
