Questions
How big is the Release PCB?
It measures 84 × 79 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Release use?
21 parts. 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 Release KiCad files?
From the LeoMaskell/squareBoy repository on GitHub, at the commit this page was made from: the board is release/pcb/pcb.kicad_pcb and its schematic PCB/pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Release 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).
