The KiCad project lives in the enkhbold470/spinner repository on GitHub; these links point at the commit this page was built from.

Spinner: common questions

What microcontroller does the Spinner use?

The Spinner is built around the STM32G431KBT6, from the STM32 family.

How big is the Spinner PCB?

The Spinner measures 84 × 66 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Spinner?

83 components, from 36 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 Spinner design files?

From the enkhbold470/spinner 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 Spinner design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which enkhbold470 chose for the repository.

Can I test firmware for the Spinner 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.
