SmSemProject: common questions

What microcontroller does the SmSemProject use?

The SmSemProject is built around the STM32WB55RGV6, from the STM32 family.

How big is the SmSemProject PCB?

The SmSemProject measures 50 × 50 mm, has 8 copper layers and is 1.6 mm thick.

How many components are on the SmSemProject?

70 components, from 34 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 SmSemProject design files?

From the Karanami/SmSemProject 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 SmSemProject design in my own project?

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

Can I test firmware for the SmSemProject 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.
