UniversalFluxInterface: common questions
What microcontroller does the UniversalFluxInterface use?
The UniversalFluxInterface is built around the STM32H723ZGT6, from the STM32 family.
How big is the UniversalFluxInterface PCB?
The UniversalFluxInterface measures 110 × 97 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the UniversalFluxInterface?
173 components, from 80 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 UniversalFluxInterface design files?
From the Axel051171/UniversalFluxInterface 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 UniversalFluxInterface design in my own project?
Yes, under the terms of its MIT license, which Axel051171 chose for the repository.
Can I test firmware for the UniversalFluxInterface 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.
