Questions
How big is the Takshaka mux board PCB?
It measures 31.6 × 24.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Takshaka mux board use?
12 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 Takshaka mux board KiCad files?
From the wendallsan/simple-multiplexer repository on GitHub, at the commit this page was made from: the board is takshaka-mux-board.kicad_pcb and its schematic takshaka-mux-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Takshaka mux board design in my own project?
Its repository states no licence, so its author keeps all rights: ask wendallsan before reusing the design.
