This is a 34-key split keyboard. It is based on the Half-Swept, but uses RP2040-Zero microcontrollers (which are smaller, generally cheaper, and can be easier to work with).

What's included

• 2x PCBs

What's not included

To assemble and operate, you will need:

• 2x Waveshare RP2040-Zero modules

• 34x Kailh Choc Key Switches + 34x compatible key caps

• 2x PJ-320D 3.5mm stereo jacks

• 1x 3.5mm TRRS cable

• 1x USB-C cable

Other Info

There are a few other modifications to the original Half-Swept:

• There is no switch

• The jacks are slightly higher up the board, and they use a SMD (PJ-320D) footprint rather than the through-hole PJ-320A (I actually used PJ-320As and bent the pins for my build).
