Questions
How big is the Alpha PCB?
It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Alpha use?
95 parts, built around the ESP-12E, TPS54202DDC, AP2114H-3.3TRG1 and M2.5. 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 Alpha KiCad files?
From the jonnor/UnlockOslo repository on GitHub, at the commit this page was made from: the board is hardware/alpha-2/alpha.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Alpha 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).
