This is Work In Progress - I'm still working on this.
It measures 285 × 94.6 mm and has 2 copper layers, 1.6 mm thick.
211 parts, built around the CH554T, TP4057, XC6206P332MR and FM-3528RGBA-HF. 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.
From the Lotlab/Lot60-BLE-Keyboard repository on GitHub, at the commit this page was made from: the board is keyboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
