Questions

How big is the Splitt Keyboard PCB?

It measures 336.8 × 150 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Splitt Keyboard use?

136 parts, built around the ESP32-S3-DEVKITC-1-N8R2 and 1N4148WT. 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 Splitt Keyboard KiCad files?

From the TomasD-git/Split-Keyboard repository on GitHub, at the commit this page was made from: the board is KiCad/Splitt Keyboard.kicad_pcb and its schematic KiCad/Left.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Splitt Keyboard design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
