Got behind with a lot of things that have come up, but it has been moving forward. Final boards done, testing almost complete, updating assembler to work with the board, finishing firmware for RP2040-zero board (provide USB HID interface and USB drive emulation for systems that do not support WEB HID in a browser), etc. Basically all the details to provide a complete, working development system. It is stereo in (TRS) then separate left and right outs so will work as mono in/out.
