BLDC driver: common questions
What microcontroller does the BLDC driver use?
The BLDC driver is built around the STM32F412CEUx, from the STM32 family.
How big is the BLDC driver PCB?
The BLDC driver measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the BLDC driver?
150 components, from 51 distinct parts. The full bill of materials is listed on this page.
Where can I download the BLDC driver design files?
From the MarijnVerschuren/BLDC_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 driver design in my own project?
Yes, under the terms of its MIT license, which MarijnVerschuren chose for the repository.
Can I test firmware for the BLDC 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.
