Hello,
While using a Pixhawk PX4 Pro, I encountered some issues due to an incorrect battery connection, which affected both the Pixhawk and the connected RFD900ux telemetry module. Below, I have detailed the problems and my observations. I would appreciate your support and suggestions for resolving these issues.
Problems Encountered:
- RFD900ux Telemetry Module:
- The port and cable of the RFD900ux module connected to the TELEM1 port were burned.
- When connected to the Pixhawk, the module emits a faint red light at 3-4 second intervals, but no light is visible when connected to a computer.
- Pixhawk TELEM1 Port:
- There is slight discoloration on the TELEM1 port.
- The port still supplies power, but telemetry communication with QGroundControl cannot be established.
- Pixhawk General Condition:
- The Pixhawk distributes power but experiences slight heating.
- The receiver and remote control connect successfully, but the SD card is not recognized.
*I tried inserting the SD card into the computer and phone, but it didn’t work. - Previously functional telemetry modules no longer establish a connection with QGroundControl via the TELEM1 or TELEM2 ports.
Possible Scenarios:
- Damage to the Pixhawk’s internal circuitry (particularly the power regulator or communication lines).
- Partial or complete failure of the TELEM1 port.
- Both TELEM1 and TELEM2 ports may be damaged.
Support Request:
- Based on these symptoms, I would like to know if the Pixhawk is repairable.
- Given that the RFD900ux module burned out while other Pixhawk functions remain operational, could the issue be limited to the telemetry ports?
- What might be causing the SD card failure and slight overheating?
- Do you recommend any hardware tests or software diagnostics?
I’m trying to find a way to reuse my Pixhawk Cube Orange by loading firmware via SD card, as I can no longer connect to it via USB. The SD card I was using before is completely damaged and unreadable.
I want to confirm whether my Cube Orange is truly dead or if there’s still a chance to recover it. From a previous parameter file I saved from QGroundControl before the issue, I know the following:
Stack: PX4 Pro
Vehicle: Fixed Wing
Version: -1.-1.-1
Git Revision: (Not available)
Is there any known method to force a firmware flash using only an SD card, especially for a situation where USB is unresponsive? Any help or insight would be greatly appreciated. Thank you!
