Questions

How big is the Modelh PCB?

It measures 150 × 38 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Modelh use?

51 parts, built around the AMS1117-3.3. 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 Modelh KiCad files?

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

Can I use the Modelh design in my own project?

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