Questions
How big is the Project X PCB?
It measures 74.4 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Project X use?
48 parts, built around the W25Q128JVPIQ and MPU-9250. 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 Project X KiCad files?
From the embeddedalpha/PCB-Design repository on GitHub, at the commit this page was made from: the board is Project X/Project X.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Project X 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).
