Questions
How big is the Frame PCB?
It measures 100 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Frame use?
52 parts, built around the MMBT3904 and SM4007. 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 Frame KiCad files?
From the RJLABS/flatcracker repository on GitHub, at the commit this page was made from: the board is HW/frame/frame.kicad_pcb and its schematic HW/NANO5/Nano5/Nano5.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Frame design in my own project?
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
