Fsorx: common questions

What microcontroller does the Fsorx use?

The Fsorx is built around the STM32L433Cx, from the STM32 family.

How big is the Fsorx PCB?

The Fsorx measures 86 × 96 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Fsorx?

152 components, from 67 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fsorx design files?

From the haunma/fieldmill repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Fsorx design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which haunma chose for the repository.

Can I test firmware for the Fsorx 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.
