Questions
How big is the Peroxide PCB?
It measures 209.5 × 80.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Peroxide use?
98 parts, built around the ATMEGA32U4-AU and USBLC6-2SC6. 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 Peroxide KiCad files?
From the rqcoon/peroxide repository on GitHub, at the commit this page was made from: the board is PCB/peroxide.kicad_pcb and its schematic PCB/peroxide.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Peroxide design in my own project?
Its repository states no licence, so its author keeps all rights: ask rqcoon before reusing the design.
