Aero: common questions

What microcontroller does the Aero use?

The Aero is built around the STM32H523CEUx, from the STM32 family.

How big is the Aero PCB?

The Aero measures 45.5 × 69.8 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Aero?

47 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Aero design files?

From the LtBrain/aero repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Aero design in my own project?

Yes, under the terms of its MIT license, which LtBrain chose for the repository.

Can I test firmware for the Aero 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.
