Greetings,
I was referred here by EMLID support in response to an email. I’ve had my Navio2 for less then a week, I was able to connect to it from missions planner, calibrate compas, gps, etc. All was well.
I returned later unable to power the navio with the power module and I was able to connect to the telemetry network only intermittently but the RGB LED is RED. Some of the components on the board are getting quite warm as well. Mainly IC9 and 11. Most sensors in mission planner are giving various warnings and wierd readings (spinning compass, -5000ft altitude, etc).
I approached my reseller, but was turned to support and then here. Help?
Had a chance to dig into this today. I ran most of the python examples that were relevant at this point. RC / Servo aren’t hooked up yet. I literally have only power and GPS plugged in. Here are the results:

it is in fact screwed down. I’ll snap a picture tonite. The hot components are pretty concerning. In the meantime, I’ve purchased another and its working flawlessly.
Also, I think its kind of odd that my reseller essentially sent me to a forum to get someone to agree that my board is not functioning before I can return / exchange it.
Will do that when i get home this evening. I received an email from one of your people today about replacement… thanks very much for taking care of this!
I’m new and building a quad with :
_D8R XP
_ESC 4 in 1
_Telemetry via UART
_RPI 3
_S500 frame
It seems that I have the same problem : the chip of my navio2 is very hot, the led lights up green during 10 sec and then remains off and the chips doesn’t want to connect anymore (it worked yesterday, no idea of what happened…). What can I do ?
Thank you for your reply.
I just tested with an other RPi (unused one, bought this morning), and the RPi is working (detected on the network, I can access with Putty etc) but still the Navio Board has the chip very hot and it seems no to be working anymore. Here is a screen shot I did today :
Also the installation of Emlid Raspbian is new (using Etcher), I have formated the SD card and reconfigured everything like before, so the problem doen’t come from the file system.
