Bldc motor cntroller: common questions

What microcontroller does the Bldc motor cntroller use?

The Bldc motor cntroller is built around the STM32F405RGTx, from the STM32 family.

How big is the Bldc motor cntroller PCB?

The Bldc motor cntroller measures 58 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Bldc motor cntroller?

130 components, from 51 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 motor cntroller design files?

From the azmat-bilal/bldc_motor_controller_pcb repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Bldc motor cntroller design in my own project?

Yes, under the terms of its MIT license, which azmat-bilal chose for the repository.

Can I test firmware for the Bldc motor cntroller 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.
