Questions
How big is the Cyclops PCB?
It measures 122.3 × 96.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cyclops use?
68 parts, built around the 74LVC1G07SE-7-MS, BQ25895RTW, CH221K and RT9742GGJ5. 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 Cyclops KiCad files?
From the furbrain/Cyclops repository on GitHub, at the commit this page was made from: the board is pcb/main/main.kicad_pcb and its schematic pcb/charger_mod/charger_mod.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cyclops design in my own project?
Its repository states no licence, so its author keeps all rights: ask furbrain before reusing the design.
