Questions

How big is the Macroboard PCB?

It measures 94 × 120.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Macroboard use?

83 parts, built around the TC1263-3.3VOA. 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 Macroboard KiCad files?

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

Can I use the Macroboard design in my own project?

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