Controller: common questions

What microcontroller does the Controller use?

The Controller is built around the STM32G031K8TX, from the STM32 family.

How big is the Controller PCB?

The Controller measures 50.8 × 50.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Controller?

54 components, from 26 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 Controller 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 Controller 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 Controller 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.
