Raspberry pi won't power up

(Maureen Byrne) #1

I almost completed the ArduSub initial setup with exception of ‘‘Configuring motor directions’’. When i power up my ROV I do not get any signals and QGroundControl wont find my device. The FAThOM -X tether interface onboard the ROV does not light up and my raspberry pi wont either. The pixhawk lights up. I use the micro USB-port to power my rasberry pi. What might be wrong? The output voltage from the Ubec voltage regulator is 0V.

If you’re following the build instructions then the UBEC is used to power the Raspberry Pi and the Fathom-X board draws power directly from the main battery supply. If the UBEC is showing an output of 0 vdc, then it’s either not connected correctly or is defective.

I would double check the instructions and make sure you’ve connected everything correctly. And then, using a voltmeter, trace the power from the battery to your components to see where the problem is.

Good luck!
