Questions
How big is the Cyton Mod PCB?
It measures 61.3 × 61.3 mm and has 4 copper layers, 1.64 mm thick.
What parts does the Cyton Mod use?
135 parts, built around the STM32L476RGT6, ADS1299IPAGR, SN74LVC1G32DCKR(AT) and TPS7A2025PDBVR-TP. 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 Cyton Mod KiCad files?
From the flosimn/Cyton-Mod repository on GitHub, at the commit this page was made from: the board is Cyton Mod Hardware/Cyton Mod/Cyton Mod.kicad_pcb and its schematic Cyton Mod Hardware/Cyton Mod/ADS1299.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cyton Mod design in my own project?
Its repository states no licence, so its author keeps all rights: ask flosimn before reusing the design.
