The KaRP2040 is a basic no-frills 34-key, wired unibody split keyboard by Jon Mereria aka jammerkiai – sporting an RP2040-Zero module running KMK.

I spent some time traveling with the wireless split keyboard I built a few months ago. While I enjoyed using it, there were some situations where I thought having a wired unibody keyboard made more sense – jammerkiai.

  • SMD diodes (SOD-123 1N4148)
