Fluxnode foc driver: common questions
What microcontroller does the Fluxnode foc driver use?
The Fluxnode foc driver is built around the STM32G474RET6, from the STM32 family.
How big is the Fluxnode foc driver PCB?
The Fluxnode foc driver measures 80 × 80 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Fluxnode foc driver?
220 components, from 65 distinct parts. The full bill of materials is listed on this page.
Where can I download the Fluxnode foc driver design files?
From the PhiMaii/fluxnode-foc-driver repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Fluxnode foc driver design in my own project?
Yes, under the terms of its CERN-OHL-P-2.0 license, which PhiMaii chose for the repository.
Can I test firmware for the Fluxnode 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.
