Pros

  • The RP2040-Zero is described as smaller, generally cheaper and easier to work with than the original controller
  • Very cheap PCB set ($8 for both PCBs)
  • Low-profile Kailh Choc switches

Cons

  • Only the PCBs are included; controllers, switches, keycaps, jacks and cables must be bought separately
  • Requires soldering and assembly
  • No power switch; wired-only design
  • Only a 34-key minimal layout, so heavy use of layers
