FOC KING: common questions

What microcontroller does the FOC KING use?

The FOC KING is built around the STM32F401CCU6_Blackpill, from the STM32 family.

How big is the FOC KING PCB?

The FOC KING measures 75.2 × 99.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the FOC KING?

238 components, from 66 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 FOC KING design files?

From the b264/FOC_KING 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 FOC KING design in my own project?

The repository has no license, so all rights stay with b264. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the FOC KING 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.
