Let's say That I want to use an arduino uno in a project where it would be subjected to all kinds of extremes. Very high and low temperature, high shock (mechanical shock, I.E. G-forces, dropping, jarring, etc.) High pressures, vacuums, etc.
Without pulling the datasheet on every single component, (and, not that I expect any of you to do this for me, just if you know off-hand or could point me a direction) what components should I be worried about?
Thanks
Crystal, and any non-soldered connections.
USB connector, power connector, maybe reset switch (dirt ingress and moisture).
Water
what components should I be worried about?
The programming skills of the person writing the code.
Very high and low temperature,
Most commercial components are only specified to work between 0 and 70C, using military grade components can push this at both ends but also pushes the cost a great deal, but you cant get much to work at below -30C and above 100C. Outside those you are better trying to engineer a climatic control for the electronics.
