No 5V Output on GPS1 Port – Holybro Pixhawk Jetson Baseboard + Pixhawk 6X

Pixhawk
1

Hi all,

I’m using a Pixhawk 6X flight controller mounted on the Pixhawk Jetson Baseboard Bundle Holybro Pixhawk Jetson Baseboard | PX4 Guide (main)

I’ve connected an mRo u-blox GPS to the GPS1 port (10-pin GH connector), but I’m not getting 5V on the VCC pin (measured between pin 1 and GND = 0V). The GPS is not powering up. From the signals pins i am able to read 3.3v.

Things I’ve checked:

  • GPS is connected correctly to GPS1 (wiring verified)
  • I’m powering the Pixhawk via PM02D power module from a 6S battery
  • Signal line shows 3.3V, but VCC is 0V

Do I need to set a specific ArduPilot parameter to enable 5V power to GPS1 on this baseboard? Or is this something controlled in hardware?

Thanks in advance for any advice!
