I buy a Pixhawk4 flight controller, and am preparing to develop a new body, but I use “QGroundControl” to find that the firmware version is 3.6.11, so I don’t know if I should download “//github.com/ArduPilot” or "/ /github.com/PX4/Firmware ", can anyone tell me how to choose?
Look through both forums, and both setup guides, to determine which best meets your use case, then make an informed decision.
