Bldc hw: common questions

What microcontroller does the Bldc hw use?

The Bldc hw is built around the C108516, from the STM32 family.

How big is the Bldc hw PCB?

The Bldc hw measures 100 × 60 mm, has 4 copper layers and is 1.765 mm thick.

How many components are on the Bldc hw?

175 components, from 49 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 hw design files?

From the igorwolfs/bldc-hw 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 hw design in my own project?

Yes, under the terms of its GPL-3.0 license, which igorwolfs chose for the repository.

Can I test firmware for the Bldc hw 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.
