Questions
How big is the Pdb PCB?
It measures 77.5 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pdb use?
118 parts, built around the ATTINY1606-SF, BD81870EFV-ME2, FT230XS-R and LM321. 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 Pdb KiCad files?
From the 0x007E/pdb repository on GitHub, at the commit this page was made from: the board is pcb/PDB.kicad_pcb and its schematic pcb/PDB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pdb design in my own project?
Its repository states no licence, so its author keeps all rights: ask 0x007E before reusing the design.
