The KiCad project lives in the trezor/trezor-hardware repository on GitHub; these links point at the commit this page was built from.

Trezor v1.1: common questions

What microcontroller does the Trezor v1.1 use?

The Trezor v1.1 is built around the STM32F205RET6, from the STM32 family.

How big is the Trezor v1.1 PCB?

The Trezor v1.1 measures 50 × 26.7 mm and is 1.6 mm thick.

How many components are on the Trezor v1.1?

46 components, from 26 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 Trezor v1.1 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 Trezor v1.1 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 Trezor v1.1 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.
