Designing hardware for −40°C and dust

A demo runs in a clean office. A deployment runs where the temperature swings seventy degrees across a year and fine dust gets into everything. Designing for the second case is a different discipline.

The edge node is sealed against dust and condensation, with thermal management that keeps inference stable from deep cold to summer heat. Power is conditioned for unreliable site supply, and the unit buffers locally so a brownout never costs you data.

None of this is glamorous, but it's the difference between a system that works in a slide deck and one that works on the third shift in February. Reliability is a feature, and at remote sites it's the most important one.
