FOC-driver: common questions
What microcontroller does the FOC-driver use?
The FOC-driver is built around the STM32G431RBT6, from the STM32 family.
How big is the FOC-driver PCB?
The FOC-driver measures 100 × 100 mm, has 4 copper layers and is 1.565 mm thick.
How many components are on the FOC-driver?
224 components, from 61 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-driver design files?
From the Froggy111/foosball-bot 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-driver design in my own project?
The repository has no license, so all rights stay with Froggy111. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the FOC-driver 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.
