About the Mechanical keyboard PCB

Mechanical keyboard is an open source RP2040/RP2350 PCB design by kavinag1, published on GitHub. It is a 4-layer board measuring 329.7 × 116 mm, with 125 components from 12 distinct parts.

Its main chip is the Raspberry_Pi_Pico, from the RP2040/RP2350 family. By type, the board carries 62 switches, 61 diodes, 1 IC and 1 capacitor.

It belongs with the keyboards designs in this gallery.

From the project

I have been wanting a mechanical keyboard. So instead of buying one why not make one. This was not really a easy journey but I am proud of what all I have learnt

I also researched switches, connectivity, and firmware. I selected EPOMAKER Creamy Jade switches because they are MX-style and compatible with standard footprints. I decided to make the keyboard wired instead of wireless to reduce complexity and allow me to use QMK firmware more easily.

Mechanical keyboard: common questions

What microcontroller does the Mechanical keyboard use?

The Mechanical keyboard is built around the Raspberry_Pi_Pico, from the RP2040/RP2350 family.

How big is the Mechanical keyboard PCB?

The Mechanical keyboard measures 329.7 × 116 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Mechanical keyboard?

125 components, from 12 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Mechanical keyboard design files?

From the kavinag1/mechanical_keyboard repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Mechanical keyboard design in my own project?

The repository has no license, so all rights stay with kavinag1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Mechanical keyboard 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.
