About the Quetzal PCB

Quetzal is an open source RP2040/RP2350 PCB design by doesntfazer, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 402.5 × 160.8 mm, with 209 components from 3 distinct parts.

Its main chip is the rp2040-zero, from the RP2040/RP2350 family. By type, the board carries 104 switches, 104 diodes and 1 IC.

It belongs with the keyboards designs in this gallery.

From the project

100% ergo keyboard based on rp2040 Zero Board

Firmware for this board will be in the Keyboard Dweebs Firmware Repository

This Board will be using PRK Firmware because of the support for Japanese duplex Matrices.

Quetzal: common questions

What microcontroller does the Quetzal use?

The Quetzal is built around the rp2040-zero, from the RP2040/RP2350 family.

How big is the Quetzal PCB?

The Quetzal measures 402.5 × 160.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Quetzal?

209 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Quetzal design files?

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

Can I use the Quetzal design in my own project?

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

Can I test firmware for the Quetzal 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.
