From the project

A completely from-scratch, bare-metal implementation of Field-Oriented Control (FOC) tailored for ultra-low inductance (~3 µH) drone motors (e.g., A2212). Built on a custom-designed STM32G4 PCB, this project bypasses heavy abstraction layers (like HAL and ST MC SDK) to achieve mi

A completely from-scratch, bare-metal implementation of Field-Oriented Control (FOC) tailored for ultra-low inductance (~3 µH) drone motors (e.g., A2212). Built on a custom-designed STM32G4 PCB, this project bypasses heavy abstraction layers (like HAL and ST MC SDK) to achieve microsecond-level execution times and maximum hardware utilization.

Blistering 40 kHz Control Loop: Pushed the STM32G4 (150 MHz) to a 25 µs execution window. Extreme Execution Efficiency: Through bare-metal register manipulation, FPU caching, and eliminating heavy libraries (fmodf), the complete FOC ISR execution time…

STM32-FOC-Control: common questions

What microcontroller does the STM32-FOC-Control use?

The STM32-FOC-Control is built around the STM32G431RBT6, from the STM32 family.

How big is the STM32-FOC-Control PCB?

The STM32-FOC-Control measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the STM32-FOC-Control?

118 components, from 36 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 STM32-FOC-Control design files?

From the Gokasimov/STM32-FOC-Control 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 STM32-FOC-Control design in my own project?

Yes, under the terms of its MIT license, which Gokasimov chose for the repository.

Can I test firmware for the STM32-FOC-Control 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.
