Stmsp: common questions

What microcontroller does the Stmsp use?

The Stmsp is built around the STM32F303CBTx, from the STM32 family.

How big is the Stmsp PCB?

The Stmsp measures 42 × 42 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Stmsp?

131 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the Stmsp design files?

From the rene-dev/stmbl repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Stmsp design in my own project?

Yes, under the terms of its GPL-3.0 license, which rene-dev chose for the repository.

Can I test firmware for the Stmsp 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.
