Sg gain link: common questions

What microcontroller does the Sg gain link use?

The Sg gain link is built around the STM32G031F6P6, from the STM32 family.

How big is the Sg gain link PCB?

The Sg gain link measures 76.2 × 89.1 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Sg gain link?

64 components, from 29 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 Sg gain link design files?

From the oats-center/avena-rs 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 Sg gain link design in my own project?

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

Can I test firmware for the Sg gain link 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.
