Questions
How big is the Ibakey52 PCB?
It measures 143.1 × 150.7 mm and has 4 copper layers, 1.2 mm thick.
What parts does the Ibakey52 use?
200 parts, built around the TPS22917DBV, 1N4148W, MPZ1608S601ATA00 and DESD5V0U1BA-7-ES. 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 Ibakey52 KiCad files?
From the Ibakha/ibakey52 repository on GitHub, at the commit this page was made from: the board is HW/ibakey52.kicad_pcb and its schematic HW/ibakey52-keys.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ibakey52 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).
