About the Piantor PCB

Piantor is an open source RP2040/RP2350 PCB design by beekeeb, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 138.8 × 89.9 mm, with 29 components from 7 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. By type, the board carries 21 relays, 2 resistors, 1 IC and 1 connector.

It belongs with the keyboards designs in this gallery.

From the project

The Piantor Keyboard is a beginner-friendly, easy-to-solder, 42-key or 36-key, diodeless, low profile aggressive column staggered, hotswappable and non-hotswappable, programmable ergonomic mechanical split keyboard powered by Raspberry Pi Pico or other compatible RP2040 boards. It is based on the Cantor Keyboard.

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".

Piantor: common questions

What microcontroller does the Piantor use?

The Piantor is built around the Pico, from the RP2040/RP2350 family.

How big is the Piantor PCB?

The Piantor measures 138.8 × 89.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Piantor?

29 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Piantor design files?

From the beekeeb/piantor repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Piantor design in my own project?

Yes, under the terms of its GPL-3.0 license, which beekeeb chose for the repository.

Can I test firmware for the Piantor without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
