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
