Is there any data regarding the operating temperature of the carambola 2 module? I was doing some testing earlier and found that the module became unstable at ambient temps above 50C. How about low end temperature?

Is there any way to sense the internal temp of the modules? I know some processors have a build in temp sensor.

Operational temperature? If that is the case why am I seeing mine consistently fail above 50C?

What fail ? WiFi, ethernet degradation, CPU , ram , flash, unstable ? Doesn't work interfaces ?
We did tests in our climate chamber from -40oC to +85 oC. From -42oC ethernet become unstable.
More than +89oC WiFi interface throughput degradation.

We did tests again and didn't find any issues.

I have done a lot more testing on this, and not gotten very consistent results. During some tests the module has been stable at 75C. During other tests it consistently and rapidly fails at 60C. One thing that seemed to make a difference was having a wifi client connected. When the module was just idle (trying to connect to an AP that wasn't on) it would fail. When I turned that AP on, it started working again. Then when I turned it off it kept working... Long story short I am still confused.
