To go to -40C you have to be careful with a lot of other components. |
6 |
Capacitors especially electrolitics will have to be carefully selected. |

-20C is probably on the edge for standard components. We also fit disk |
8 |
heaters although these days we'd suggest solid state data storage. |

Several of the big little board manufacturers offer extended temperature |
11 |
ranges, but they charge premium prices for them, and are expensive for |
12 |
one off projects. |

14 |
I'd suggest going with best domestic range board you can get and then |
15 |
try to protect it from the extremes in some way. Bury it a few feet |
16 |
under ground snuggled up to a large thermal mass like the battery. Out |
17 |
of the wind a few feet under temperatures should stablise around about |
18 |
-4C. |
