We are getting an overtemperature alarm even when the housing for the electronics enclosure is removed. Where is the internal temperature senor located?  
Thanks!

Hi @gcelec,

Assuming this is an error that’s coming up in QGC, the Pixhawk barometer (which includes a temperature sensor) is underneath the 3 pin “ADC 6.6V” header (on the flip side of the PCB), indicated here on the view from the bottom of the Pixhawk:

When mounted it would be just over the red power LED on the Raspberry Pi.
