Questions
How big is the CyberTrust PCB?
It measures 31.6 × 48.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CyberTrust use?
43 parts, built around the W25Q128JVSIQ, ABM8-272-T3 and WS2812B. 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 CyberTrust KiCad files?
From the Aahil78/CyberTrust repository on GitHub, at the commit this page was made from: the board is src/CyberTrust.kicad_pcb and its schematic src/CyberTrust.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CyberTrust design in my own project?
Its repository states no licence, so its author keeps all rights: ask Aahil78 before reusing the design.
