This is a project that was inspired by ZSA's Moonlander and Voyager split keyboards. I loved how they looked and with my move to a keyboard-driven workflow, I decided that I needed to make the move. I started second-guessing myself when I saw the price, as I was a student, and I came to the realisation that I had the skills to design one.

TheFalcon Panel: common questions

What microcontroller does the TheFalcon Panel use?

The TheFalcon Panel is built around the C529355, from the STM32 family.

How big is the TheFalcon Panel PCB?

The TheFalcon Panel measures 185.7 × 303.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the TheFalcon Panel?

334 components, from 57 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 TheFalcon Panel design files?

From the Matthew-Hammon/TheFalcon 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 TheFalcon Panel design in my own project?

Yes, under the terms of its MIT license, which Matthew-Hammon chose for the repository.

Can I test firmware for the TheFalcon Panel without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
