From the project
The primary objective is to create an alternative to the difficult-to-source off-the-shelf Pixhawk 6. This work builds upon a edited pixracer version produced by KAI (Wesley) in 2022.

QUT Autopilot Pixracer: common questions
What microcontroller does the QUT Autopilot Pixracer use?
The QUT Autopilot Pixracer is built around the STM32F427VIT6, from the STM32 family.
How big is the QUT Autopilot Pixracer PCB?
The QUT Autopilot Pixracer measures 44.5 × 44.5 mm, has 4 copper layers and is 0.6234 mm thick.
How many components are on the QUT Autopilot Pixracer?
140 components, from 56 distinct parts. The full bill of materials is listed on this page.
Where can I download the QUT Autopilot Pixracer design files?
From the Heckus/QUT-OpenFCU repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the QUT Autopilot Pixracer design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
Can I test firmware for the QUT Autopilot Pixracer 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.
