Questions

How big is the Lokkey PCB?

It measures 371.6 × 123.9 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Lokkey use?

242 parts, built around the RP2040, W25Q128JVSIQ 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 Lokkey KiCad files?

From the An0lys/lokkey repository on GitHub, at the commit this page was made from: the board is Lokkey.kicad_pcb and its schematic Lokkey.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Lokkey design in my own project?

Its repository states no licence, so its author keeps all rights: ask An0lys before reusing the design.
