Questions

How big is the Prototype mk1 panel PCB?

It measures 320 × 126 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Prototype mk1 panel use?

283 parts. 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 Prototype mk1 panel KiCad files?

From the H0N3YC4T/prototype-mk1 repository on GitHub, at the commit this page was made from: the board is docs/PCB/panel/prototype-mk1_panel.kicad_pcb and its schematic docs/PCB/mounting_plate/prototype-mk1_top.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Prototype mk1 panel design in my own project?

Its repository states no licence, so its author keeps all rights: ask H0N3YC4T before reusing the design.
