Nitrokey Pro: common questions

What microcontroller does the Nitrokey Pro use?

The Nitrokey Pro is built around the 497-11534, from the STM32 family.

How big is the Nitrokey Pro PCB?

The Nitrokey Pro measures 21.8 × 16.3 mm and is 1 mm thick.

How many components are on the Nitrokey Pro?

39 components, from 21 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 Nitrokey Pro design files?

From the Nitrokey/nitrokey-start-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 Nitrokey Pro design in my own project?

The repository has no license, so all rights stay with Nitrokey. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Nitrokey Pro 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.
