Questions

How big is the Arm PCB?

It measures 95 × 70 mm and has 6 copper layers, 1.6 mm thick.

What parts does the Arm use?

185 parts, built around the LT8912B, W25Q128JVSIQ, USBLC6-2SC6 and MTFC16GAPALBH-IT. 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 Arm KiCad files?

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

Can I use the Arm design in my own project?

Its repository publishes it under the Apache-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).
