I am playing with developping autopilots... One of the issues I have is the requirement for low temperatures - 40 - 50°C.
I have found a couple of posts which state that Teensy 3.2 is basically good for -20 C (or -10 C), one issue being the crystal and the other possible contraction/expansion of the board for long term robustness.
With reference to Teensy 3.5, 3.6 and 4.0: what is the safe operational temperature? I need at least -40 C to +60 C...
I can make a small heater from a network of resistors (I do so for sevoes, basically, you poor epoxy with microbaloons around the case and embed 8-10 1/8 W resistors: 1 Watt heats a small servo to a delta of 20-25 C.
Is it safe to poor epoxy over the teensy boards? The temperature limitations are with reference to the processor, to the part of the board where the processor is soldered, or to the whole board? i.e. is it necessary to heat just the top of the processor, or the processor and the other side of the board? Heating the whole board evenly without enclosure is more complicated.
So far I have been using Arduine pro 2560 without any glitches and without heating...
