Questions
How big is the Beta PCB?
It measures 50 × 108 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Beta use?
58 parts, built around the SN74AHCT125N, TLV274D, W25Q32FVSSIG and LM1117-3.3. 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 Beta KiCad files?
From the wntrblm/Sol repository on GitHub, at the commit this page was made from: the board is hardware/beta/mainboard/mainboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Beta design in my own project?
Its repository states no licence, so its author keeps all rights: ask wntrblm before reusing the design.
