Sf motion: common questions

What microcontroller does the Sf motion use?

The Sf motion is built around the STM32F405RGTX, from the STM32 family.

How big is the Sf motion PCB?

The Sf motion measures 60 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sf motion?

123 components, from 46 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 Sf motion design files?

From the sirojudinMunir/sf-motion 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 Sf motion design in my own project?

Yes, under the terms of its MIT license, which sirojudinMunir chose for the repository.

Can I test firmware for the Sf motion 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.
