Questions
How big is the Baggerdails PCB?
It measures 75 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Baggerdails use?
61 parts, built around the CH330N, AT24C256C-SSHL-T, ATECC608A-MAHDA-S and USBLC6-2SC6. 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 Baggerdails KiCad files?
From the Linutronix/baggerdails repository on GitHub, at the commit this page was made from: the board is baggerdails.kicad_pcb and its schematic baggerdails.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Baggerdails design in my own project?
Its repository states no licence, so its author keeps all rights: ask Linutronix before reusing the design.
