Hello
The switch on the esp32 module resets the multiplexer. The multiplexer starts working with the existing settings. It is the same as an interruption of the power supply. The switch on the pcb is a hard reset. The multiplexer starts working not with existing settings but with the factory settings.

In the improbable case you need to test the hardware

Re: In the improbable case you need to test the hardware
Hello Carlo,
Please answer the following question:
- when you do the "factory reset" by pressing and holding the SW1 switch, do the RED and GREEN led stay ON for about 2 seconds? If yes you release the switch when both leds go OFF!
If the Leds stay ON during the reset as explained above, do not take the leds off of the PCB. They are OK. If their polarity was wrong they will be allays OFF.
Waiting for your answer, Regards, Luis

Hello,
The square pads are connected to GND and so are the cathodes, as you can see in the circuit diagram.
If they are not, please invert their polarity.
