BLDC 4: common questions

What microcontroller does the BLDC 4 use?

The BLDC 4 is built around the STM32F40X_LQFP64, from the STM32 family.

How big is the BLDC 4 PCB?

The BLDC 4 measures 38.5 × 65 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BLDC 4?

123 components, from 52 distinct parts. The full bill of materials is listed on this page.

Where can I download the BLDC 4 design files?

From the KoJZz/Control-Rakatuy repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the BLDC 4 design in my own project?

The repository has no license, so all rights stay with KoJZz. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the BLDC 4 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.
