Questions

How big is the Arm 20to10 PCB?

It measures 16.9 × 29.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Arm 20to10 use?

10 parts, built around the 20021111-00010T4LF, SFH11-PBPC-D10-RA-BK and SSSS810701. 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 20to10 KiCad files?

From the noahp/arm_20to10 repository on GitHub, at the commit this page was made from: the board is arm_20to10.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Arm 20to10 design in my own project?

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