I just build my redox keyboard and I found a problem about the right hand side is not working when connecting via the TRRS cable

    Im not familiar with the redox, but i see you got two unpopulated resistor footprints around the trrs connector.

    Are you sure the resistors are optional?

      I think this is the answer, there might be more issues with the state of the soldering but the build guide says it needs them (indicating they’re using i2c for split comms).

      OP needs to add 2x 4.7kOhm resistors on one half of the keyboard.
