Questions

How big is the Sacred65 PCB?

It measures 304.8 × 95.2 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Sacred65 use?

195 parts, built around the RP2040 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 Sacred65 KiCad files?

From the LordsBoards/Sacred65 repository on GitHub, at the commit this page was made from: the board is Sacred65.kicad_pcb and its schematic Sacred65.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Sacred65 design in my own project?

Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
