Questions
What parts does the Chugjug use?
45 parts, built around the LIS3DH, TPS78233DDCR and RLSD52A051V. 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 Chugjug KiCad files?
From the owenpark8/chugjug repository on GitHub, at the commit this page was made from: the board is hw/chugjug.kicad_pcb and its schematic hw/chugjug.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chugjug design in my own project?
Its repository states no licence, so its author keeps all rights: ask owenpark8 before reusing the design.
