Questions
How big is the CYM1A113 PCB?
It measures 59 × 33.8 mm and has 4 copper layers, 1 mm thick.
What parts does the CYM1A113 use?
133 parts, built around the STM32F427VIT6, MIC803-29D2VC3-TR, XC6210B332PR-G and DMP2045U. 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 CYM1A113 KiCad files?
From the trezor/trezor-hardware repository on GitHub, at the commit this page was made from: the board is electronics/trezor_model_t/kicad/CYM1A113.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CYM1A113 design in my own project?
Its repository states no licence, so its author keeps all rights: ask trezor before reusing the design.
