Questions
How big is the Matenode PCB?
It measures 76 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Matenode use?
107 parts, built around the ESP32-C3-WROOM-02-H4, PAM8302AADCR, BQ24073RGTR and SPX3819M5-L-3-3. 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 Matenode KiCad files?
From the cr1tbit/matenode repository on GitHub, at the commit this page was made from: the board is matenode.kicad_pcb and its schematic matenode.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Matenode design in my own project?
Its repository states no licence, so its author keeps all rights: ask cr1tbit before reusing the design.
