FEZ Hydra operating temp

The doc says:
•Operating temperature: 0 to 70°C

Is this a board design for mostly tropical climates or can it do -20C like the other boards?


Rated 0 to 70 as catalog shows.

What kind of problems are we faced if we use Hydra in places with a temperature below zero?

It may or may not work.

Or worse, work erratically.

although a quick polystyrene foam insulation case would make this largely a non-issue.

Does Hydra have a linear regulator onboard? The USB DP doesn’t, right? Easy enough to dissipate some heat from a simple resistor, though, and heat a well-insulated enclosure a few degrees.
