Questions
How big is the Gummy60 PCB?
It measures 284.7 × 94.2 mm and has 2 copper layers, 1.2 mm thick.
What parts does the Gummy60 use?
128 parts, built around the ATMEGA32U4-MU, CPG151101S11 and BAV70. 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 Gummy60 KiCad files?
From the arnstadm/gummy repository on GitHub, at the commit this page was made from: the board is gummy60.kicad_pcb and its schematic gummy60.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gummy60 design in my own project?
Its repository states no licence, so its author keeps all rights: ask arnstadm before reusing the design.
