Commander: common questions

What microcontroller does the Commander use?

The Commander is built around the STM32G431CBU6, from the STM32 family.

How big is the Commander PCB?

The Commander measures 45 × 20 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Commander?

43 components, from 27 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 Commander design files?

From the kuku-199/Afflatus 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 Commander design in my own project?

The repository has no license, so all rights stay with kuku-199. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Commander 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.
