Questions
How big is the Switchboard mk1 PCB?
It measures 87 × 26 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Switchboard mk1 use?
17 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 Switchboard mk1 KiCad files?
From the chuanqisun/micro-controller-programming repository on GitHub, at the commit this page was made from: the board is board/archives/switchboard-mk1/switchboard-mk1.kicad_pcb and its schematic board/archives/agent-box-poc/agent-box.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Switchboard mk1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask chuanqisun before reusing the design.
