Questions
How big is the Root access PCB?
It measures 38.5 × 28.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Root access use?
21 parts, built around the BQ24074RGTR and SHT31-DIS-F. 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 Root access KiCad files?
From the Bobev64/root_access_board repository on GitHub, at the commit this page was made from: the board is root_access/root_access.kicad_pcb and its schematic root_access/root_access.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Root access 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).
