My wish is to bring out a pcb card, which is prepared with headers. So I can solder wires between the esp32 dev board and the new pcb myself. (Depending on price I maybe want the esp32 integrated on the board but I am not that knowledgeable in pcb creation what is required. if so, you could program it via usb-c. 5v should be taken to the relay directly from usb 5v. I am happy to listen to suggestions) The relay modules i currently use have the signal wire dangerously close to the NC screw terminal.. Im using 230VAC and i want to use the best practice to avoid the high voltage separated from the ”low” voltage… (adding image how I don't want it) I would like to use 5.08mm Pitch screw terminals Here is schematic for the modules i want to integrate Re...
