FOC Control Boards: common questions

What microcontroller does the FOC Control Boards use?

The FOC Control Boards is built around the STM32G431CBT6, from the STM32 family.

How big is the FOC Control Boards PCB?

The FOC Control Boards measures 81 × 80.9 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the FOC Control Boards?

106 components, from 46 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 Control Boards design files?

From the coopjz/FOC_Control_Boards 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 Control Boards design in my own project?

Yes, under the terms of its MIT license, which coopjz chose for the repository.

Can I test firmware for the FOC Control Boards 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.
