split keyboard V2

This is V2 of my split keyboard. It features a removable trrs cable, stronger and lower design and a improved sound thanks to the new case design. This keyboard project is a great step into the hobby of low-cost split ergonomic keyboards (Prices may wary but i was able to build it for $27). 

the firmware is anivailable on my github

recomended parts are listed down below(given firmware, without any modifications, will only work with the rp2040 pro micro)
