Alternative button wiring #79

Closed RBEGamer closed 7 months ago

RBEGamer commented 11 months ago

After unsoldering the old microcontroller from the PCB, it is possible to use the 7th pin for the button connection. Using this the original wiring of the button can be the same. The other end of the button pin is already connected to ground on the PCB. Here the brown wire is connected to GPIO16 of the ESP32.

An alternative is to use the left pad (in printing direction the lower pad) of C6. Soldering is easier here compared to uC pin.

Works, you can see the traces between the two pads.
