I am working with a verdex 600 MHz / robostix / netwifi-microSD for power
grid applications. We are trying to package the boards into a single, small
box (approx 130 x 80 x 30 mm). However, the heat build-up in this box is
such that when the box reaches about 95 degrees the netwifi board stops
working completely and I have to power cycle the boxes to restore
It seems strange that the verdex boards are rated up to 85 C but the netwifi
boards cease to operate when the internal temperature of our enclosure
reaches about 37 to 40 C.
I suppose I could scale back the clock speed on the verdex but I think the
major source of the heat is the netwifi board. We didn't have these
problems in our previous assemblies using a 400 MHz connex and wifi stick.
Has anyone else run into overheating failure of the new netwifi boards?
Thank you in advance for any advice or suggestions you may have.
