Questions
What parts does the CuHum Main use?
53 parts, built around the MPR121QR2, MAX98357AETE+T, MT2492 and W25Q16JVSSIQ. 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 CuHum Main KiCad files?
From the ayuusweetfish/Humming-Cumulus repository on GitHub, at the commit this page was made from: the board is Main_Board/hw/CuHum_Main.kicad_pcb and its schematic Cloud_Unit/hw/Clouds.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CuHum Main design in my own project?
Its repository states no licence, so its author keeps all rights: ask ayuusweetfish before reusing the design.
