About the CAN-BUS-FOC-Actuator PCB

CAN-BUS-FOC-Actuator is an open source STM32 PCB design by f1133, published on GitHub. It is a 2-layer board measuring 60 × 60 mm, with 73 components from 33 distinct parts.

Its main chip is the STM32G431CBT6, from the STM32 family. Other key parts include the SN65HVD230DR, INA240A1DR, SimpleFOC Mini and AMS1117-3.3. By type, the board carries 23 resistors, 22 capacitors, 11 connectors, 6 ICs, 2 LEDs and 1 crystal.

CAN-BUS-FOC-Actuator design files

The KiCad project lives in the f1133/CAN-BUS-FOC-Actuator repository on GitHub; these links point at the commit this page was built from.

CAN-BUS-FOC-Actuator: common questions

What microcontroller does the CAN-BUS-FOC-Actuator use?

The CAN-BUS-FOC-Actuator is built around the STM32G431CBT6, from the STM32 family.

How big is the CAN-BUS-FOC-Actuator PCB?

The CAN-BUS-FOC-Actuator measures 60 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CAN-BUS-FOC-Actuator?

73 components, from 33 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 CAN-BUS-FOC-Actuator design files?

From the f1133/CAN-BUS-FOC-Actuator 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 CAN-BUS-FOC-Actuator design in my own project?

The repository has no license, so all rights stay with f1133. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the CAN-BUS-FOC-Actuator 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.
