Bldc esc
About the Bldc esc PCB
Bldc esc is an open source STM32 PCB design by EwoudVV, published on GitHub. It is a 4-layer board measuring 544 × 768 mm, with 421 components from 124 distinct parts.
Its main chip is the STM32G474VET6, from the STM32 family. Other key parts include the TLV9024PWR, DRV8353SRTAT, INA241A2IDR, TLV3011BIDBVR and UCC27511ADBVR. By type, the board carries 173 resistors, 140 capacitors, 41 ICs, 31 diodes, 17 connectors and 8 transistors.
It belongs with the robotics & motion, sensors and test & measurement designs in this gallery.
From the project
A custom STM32 motor controller for BLDC and PMSM motors.
I want to build a small vesc like controller, with hall sensors, current sensing, regen, and enough hardware to try FOC later. The first motor is a 26 V Groschopp gearmotor, but the board should be useful for other motors too.
finished another pass through the reference supply, reset circuit, BOM and connectors. there's 16 subsheets, all on A3 or A4. the pcb has 449 footprints in the staging grid, still no placement or routing

Bldc esc: common questions
What microcontroller does the Bldc esc use?
The Bldc esc is built around the STM32G474VET6, from the STM32 family.
How big is the Bldc esc PCB?
The Bldc esc measures 544 × 768 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Bldc esc?
421 components, from 124 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 Bldc esc design files?
From the EwoudVV/bldc-esc 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 Bldc esc design in my own project?
The repository has no license, so all rights stay with EwoudVV. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Bldc esc 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.
