Hello everyone,

I came across this GitHub repository that provides hardware design files for **Pixhawk FMUv3\_REV\_D** :  
👉 [https://github.com/Nguyen-said/Hardware/tree/master/FMUv3\_REV\_D](https://github.com/Nguyen-said/Hardware/tree/master/FMUv3_REV_D)

I would like to ask for advice from the community:

- Is this hardware design **trustworthy and accurate** enough to be used as a reference?

- Can I really manufacture a board **exactly based on these files** and expect it to work properly as a Pixhawk flight controller?

- Has anyone here ever tried building a Pixhawk from open-source design files like these? If yes, what challenges should I be aware of (component sourcing, PCB layer stack, firmware compatibility, calibration, etc.)?

- Or would you recommend using an official design (e.g., from PX4 / ArduPilot GitHub) instead of this repo?

I’m currently studying and experimenting with **flight controller / Pixhawk hardware design** , so I want to make sure I don’t rely on something inaccurate or incomplete. Any feedback, experiences, or warnings would be greatly appreciated!

Thank you in advance!
