Questions

How big is the Panel PCB?

It measures 87 × 97 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Panel use?

88 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 Panel KiCad files?

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

Can I use the Panel design in my own project?

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