Overview
Keybird42 is an open-source printed circuit board by fanf2, from the fanf2/kbd repository on GitHub. It is a 2-layer board of 420.3 × 95.3 mm with 174 parts on 122 nets, routed with 1,030 tracks and 370 vias.
It is built around the RP2040-TINY, 1N4148W and F18. Its parts include 86 diodes, 78 switches and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.

README
README.mdTony Finch's keyboard projects
This repository is where I keep my work on custom mechanical keyboards.
HHKBeeb
The first keyboard I built is a tribute to the BBC Micro made in the run-up to its 40th anniversary in 2021.
It uses a Yiancar HS60 PCB and a generic HHKB case, and keycaps designed by me and printed by WASD.
The project directory hhkbeeb also contains designs for an acrylic sandwich case that I never made.
The default branch in this repository is jokingly called
model-bbecause git's default branch used to bemaster, and both are kinds of BBC Micro.
Keybird69
In 2023 I designed a 65% keyboard with a "unix69" layout. It uses a Waveshare RP2040-Tiny controller on a PCB designed by me. The case is a sandwich of FR-4 and LEGO.
I have assembled three versions of Keybird69:
-
with Cherry MX Clear switches and Signature Plastics DSS "Dolch" keycaps
-
Cherry MX Clear switches again but with the springs lubericated to eliminate their pinging; and with matt3o's GMK MTNU Susu keycaps.
-
Gateron CAP milky brown switches with JTK HSA Hyperfuse keycaps
Keybird42
My late 2023 / early 2024 work in progress is series of 77% boards:
- bigger than 75%
- fewer keys than 80%
- more symmetrical
They are called keybird42:
- 42 cm wide PCB
- 21 keys wide (42 / 2)
- 84 keys total (42 * 2)
The first version will have a layered acrylic case; there may be others.

Questions
How big is the Keybird42 PCB?
It measures 420.3 × 95.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keybird42 use?
174 parts, built around the RP2040-TINY, 1N4148W and F18. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Keybird42 KiCad files?
From the fanf2/kbd repository on GitHub, at the commit this page was made from: the board is keybird42/pcb/keybird42.kicad_pcb and its schematic iobird-1/iobird/iobird.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keybird42 design in my own project?
Its repository states no licence, so its author keeps all rights: ask fanf2 before reusing the design.
