PassPress STM: common questions

What microcontroller does the PassPress STM use?

The PassPress STM is built around the STM32F042G6U6TR, from the STM32 family.

How big is the PassPress STM PCB?

The PassPress STM measures 42.6 × 19.1 mm, has 4 copper layers and is 0.8 mm thick.

How many components are on the PassPress STM?

34 components, from 20 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 PassPress STM design files?

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

Can I use the PassPress STM design in my own project?

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

Can I test firmware for the PassPress STM 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.
