Questions
How big is the BeagleBark PCB?
It measures 9.7 × 17.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the BeagleBark use?
19 parts, built around the CH340E, XC6206P332MR and LESD5D5.0CT1G. 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 BeagleBark KiCad files?
From the Grippy98/Beagle-Serial-Adapter repository on GitHub, at the commit this page was made from: the board is BeagleBark.kicad_pcb and its schematic BeagleBark.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BeagleBark design in my own project?
Its repository publishes it under the GPL-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).
