Questions
How big is the Buddhabox PCB?
It measures 48.3 × 22.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Buddhabox use?
51 parts, built around the RP2040, PAM8302AADCR, W25Q32JVZPIQ and BAT54C. 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 Buddhabox KiCad files?
From the emeb/RP2040_Projects repository on GitHub, at the commit this page was made from: the board is buddhabox/hw/buddhabox.kicad_pcb and its schematic buddhabox/hw/buddhabox.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Buddhabox 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).
