Questions
How big is the Sol PCB?
It measures 40 × 108 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sol use?
59 parts, built around the OPA388ID, OPA4197ID, SN74AHCT125N and W25Q32FVSSIG. 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 Sol KiCad files?
From the wntrblm/Sol repository on GitHub, at the commit this page was made from: the board is hardware/rev1/mainboard/mainboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sol design in my own project?
Its repository states no licence, so its author keeps all rights: ask wntrblm before reusing the design.
