Questions
How big is the Chonc60 PCB?
It measures 297 × 132 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chonc60 use?
365 parts, built around the MDBT50Q-1MV2, SN74LV1T34DBV, TPS61092RSA and SK6812MINI-E. 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 Chonc60 KiCad files?
From the mildlyfunctionalgays/chonc60 repository on GitHub, at the commit this page was made from: the board is main/main.kicad_pcb and its schematic main/keyswitches.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chonc60 design in my own project?
Its repository states no licence, so its author keeps all rights: ask mildlyfunctionalgays before reusing the design.
