SPIN: common questions

What microcontroller does the SPIN use?

The SPIN is built around the STM32G474RE, from the STM32 family.

How big is the SPIN PCB?

The SPIN measures 21 × 51 mm, has 4 copper layers and is 1.59 mm thick.

How many components are on the SPIN?

34 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the SPIN design files?

From the owntech-foundation/SPIN repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SPIN design in my own project?

The repository has no license, so all rights stay with owntech-foundation. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SPIN 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.
