Questions
How big is the Dlocker PCB?
It measures 170 × 115 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Dlocker use?
17 parts, built around the RASPBERRY PI ZERO 2 W. 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 Dlocker KiCad files?
From the Marc-Blanco/Dlocker repository on GitHub, at the commit this page was made from: the board is PCB/Dlocker.kicad_pcb and its schematic PCB/Dlocker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dlocker design in my own project?
Its repository states no licence, so its author keeps all rights: ask Marc-Blanco before reusing the design.
