Questions
How big is the Minisumo PCB?
It measures 80 × 36.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Minisumo use?
53 parts, built around the ESP-WROOM-32D, TA6586, AMS1117-3.3 and WS2812B-B/T. 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 Minisumo KiCad files?
From the Toxtxo19/MiniPaltin repository on GitHub, at the commit this page was made from: the board is Main/minisumo.kicad_pcb and its schematic Main/minisumo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minisumo design in my own project?
Its repository states no licence, so its author keeps all rights: ask Toxtxo19 before reusing the design.
