Dear all, we developed a compact flight controller based on PX4, and we’ve been testing it for a year. We are willing to contribute to the community by fully open-source all hardware design(Github). This flight controller is now widely used in my research and that of my teammates(HKUST_UAV_Group).
This flight controller is now available on taobao, and soon will be sold globally.

It is amazing that you are making your work available to the community!
I guess you should open PR with your design here GitHub - pixhawk/Hardware: PX4 Hardware designs
@rroche or @hamishwillee is it enough to follow the existing documentation for the board and then open PR?
Hi
Great work
Can we test this flight controller through a gazebo simulator OR even uploaded it to a Pixhawk cube.
Theoretically, It supports hardware in loop. (Since our research focuses more on perception, we have not tested the simulation yet.) It can not be uploaded on Cube.

Hi,
thank you for the information.
a) Does it have analogue to digital converter port.
b) How many sbus port can it support
c) Which version of the NxtPX4 ( is it 1.1.3 ? ) are you selling thro ’ Tabao
d) Does it support NMEA GPS devices or only uBLOX
Hey @Peize-Liu, congrats on the project. I think the first step is to submit a pull request to PX4-Autopilot to add support for your hardware. Then, you can add your hardware to our docs, and we can also include it on the PX4 website.
One thing I will ask is that you please consider PX4 is a registered trademark that is owned by Dronecode, perhaps you want to choose a new name?
Thank you for your advice, I see it is not that suitable to call it xxxPX4. I will change the name.
Thank you @Peize-Liu I appreciate your help with the name.
Please feel free to reach out to me via email if you need help
