Questions
How big is the Foxboard PCB?
It measures 360.7 × 137.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Foxboard use?
219 parts, built around the RP2040, W25Q128JVSIQ, CR-05FL7---5K1 and ABM8-272-T3. 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 Foxboard KiCad files?
From the Lunarequest/foxboard repository on GitHub, at the commit this page was made from: the board is kicad/foxboard/foxboard.kicad_pcb and its schematic kicad/foxboard/foxboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Foxboard design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
