Open hardware wallet lab: common questions

What microcontroller does the Open hardware wallet lab use?

The Open hardware wallet lab is built around the STM32L476RET6, from the STM32 family.

How many components are on the Open hardware wallet lab?

90 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the Open hardware wallet lab design files?

From the HavenlonLabs/open-hardware-wallet-lab repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the Open hardware wallet lab design in my own project?

Yes, under the terms of its Apache-2.0 license, which HavenlonLabs chose for the repository.

Can I test firmware for the Open hardware wallet lab 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.
