Questions
How big is the Garden MUX PCB?
It measures 46 × 46 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Garden MUX use?
56 parts, built around the AP2112K-3.3, ESP32-C6-MINI-1, TL6330AF200Q and AO3401A. 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 Garden MUX KiCad files?
From the Sunewst/garden-microcontroller repository on GitHub, at the commit this page was made from: the board is Garden-MUX/Garden-MUX.kicad_pcb and its schematic Garden-MUX/Garden-MUX.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Garden MUX design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
