Cheapino is an open-source hardware design for an affordable 36-key split ergonomic keyboard, including reversible PCB files, OpenSCAD case designs, and build/ordering guides. It uses a single RP2040-Zero MCU with a japanese duplex matrix over RJ45 and supports Vial or custom QMK firmware.

Use cases

  • build a cheap split ergonomic keyboard
  • order and solder a DIY 36-key keyboard PCB
  • customize keyboard firmware with QMK or Vial
  • 3D print a case for a hotswap split keyboard
  • learn to build an ergomech keyboard on a budget

When to choose

  • you want a very low-cost DIY split keyboard with full design files and guides
  • you want a 36-key layout with hotswap or soldered options
  • you want Vial/QMK support and a single-MCU design

When to avoid

  • you want a pre-built, ready-to-use keyboard
  • you need more than 36 keys or wireless out of the box
  • you are not comfortable soldering or sourcing parts yourself
