Please tell us if you figured it out. I can send a picture in about a week.
I’ve had connected the audioinjector and all-in-one board with the ribbon cable, but I need to connect the encoders and don’t know the equivalence between the KY-040 and 4-pin JST connectors from all-in-one board.
Today I received the audio jacks and I’ll to solder at night. Once I have all hardware working, will start to project the box.
