PMSM driver: common questions

What microcontroller does the PMSM driver use?

The PMSM driver is built around the STM32F446RETx, from the STM32 family.

How big is the PMSM driver PCB?

The PMSM driver measures 81.5 × 47 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PMSM driver?

62 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the PMSM driver design files?

From the Mohamed-Ashrf/PMSM_driver repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the PMSM driver design in my own project?

Yes, under the terms of its MIT license, which Mohamed-Ashrf chose for the repository.

Can I test firmware for the PMSM driver 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.
