From the project
BLDC Motor Driver hardware and firmware project including power stage, gate driver, protection circuits, and control firmware for sensor-based and/or sensorless BLDC motors.
A compact, high-efficiency, 3-phase Field-Oriented Control (FOC) motor controller designed for high-power robotics, e-mobility, and industrial automation. Built on the STM32G431RBT6 ARM Cortex-M4 MCU and the TI DRV8353HRTAR smart gate driver, this board supports high-frequency switching up to 100 kHz with extensive hardware protection, sensor feedback, and connectivity.

BLDC Motor Driver: common questions
What microcontroller does the BLDC Motor Driver use?
The BLDC Motor Driver is built around the STM32G431RBT6, from the STM32 family.
How big is the BLDC Motor Driver PCB?
The BLDC Motor Driver measures 123.5 × 58 mm, has 8 copper layers and is 1.584 mm thick.
How many components are on the BLDC Motor Driver?
223 components, from 58 distinct parts. The full bill of materials is listed on this page.
Where can I download the BLDC Motor Driver design files?
From the AhmedAbo-Eita/BLDC_Motor_Driver repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the BLDC Motor Driver design in my own project?
The repository has no license, so all rights stay with AhmedAbo-Eita. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the BLDC Motor 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.
