The Piantor Keyboard is a 42-key or 36-key wired, diodeless, non-flippable, low profile choc v1 (hybrid hotswap and non-hotswap/soldered-in), aggressive column staggered, programmable ergonomic mechnical split keyboard powered by Rasyberry Pi Pico or other compatible RP2040 boards. It is based on the Cantor Keyboard. The name "Piantor" is the portmanteau of "Pico" and "Cantor".

Ordering Parts

DIY kits and prebuilt keyboards are available at https://beekeeb.shop

If you prefer getting the parts by yourself, you can order the Left Side PCB and the Right Side PCB.

A single side should cost around $31 for 5 pcs excluding shipping. For both sides, it should be around $62 in total for 5 sets.

Firmware Status

Precompiled firmware can be found at https://docs.beekeeb.com/piantor-keyboard.

Cases

Piantor Case with a Switch Plate (3D Printable)

Piantor Keyboard Case

Piantor Keyboard Case

The 3D printable case can be founded in the case folder. The switch plate is optional for the non-hotswap version.

GB823 M2 stainless steel screws with small pan heads are recommended.

Do not over-tighten the screws.

Cantor Tray Case

The Cantor Tray Case by chewiedies can be used. There is not a switch plate so it is not recommended for the hotswap version.
