CYM1A113: common questions

What microcontroller does the CYM1A113 use?

The CYM1A113 is built around the STM32F427VIT6, from the STM32 family.

How big is the CYM1A113 PCB?

The CYM1A113 measures 59 × 33.8 mm and is 1 mm thick.

How many components are on the CYM1A113?

132 components, from 48 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the CYM1A113 design files?

From the trezor/trezor-hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the CYM1A113 design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the CYM1A113 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
