No — I couldn't find any Jetson Thor developer kits rated down to -40 °C. NVIDIA's own Thor-family developer kits (Jetson Thor and IGX Thor, 7 kits total in the NVIDIA Hardware catalog) all fail this requirement: the developer kits that list a minimum operating temperature are rated to 0 °C or 5 °C, and none reaches -40 °C. So the answer for developer kits specifically is: not available.
If -40 °C is a hard requirement, the closest verified alternatives are partner products built on the Jetson Thor T5000/T4000 modules — enclosed full systems rather than developer kits. These are ready-to-run computers you can develop on directly:

| Product | Partner | Catalog type | Temp range |
|---|---|---|---|
| MILBOX-THR | Forecr | Edge AI Box PC (Full System) | -40 to 70 °C |
| Condor T5-IOX 3U VPX | EIZO Rugged Solutions | Modular Compute Board (Full System) | -40 to 85 °C |
| RTSS-X407 | Realtimes | Embedded AI System (Full System) | -40 to 60 °C |
| RTSS-X406 | Realtimes | Embedded AI System (Full System) | -40 to 60 °C |
| RTS-AGT700 | Realtimes | Embedded AI System (Full System) | -40 to 60 °C |
| RTS-AGT600 | Realtimes | Embedded AI System (Full System) | -40 to 60 °C |
There are also 10 partner carrier boards rated to -40 °C that take a Jetson Thor module — from Realtimes (RTSO-4002, RTSO-4006, RTSO-4007), Forecr (DSBOARD-THRMAX, MILBOARD-THR), Connect Tech (Gauntlet, Rogue-T5), AVerMedia (D331, D333 Panther), and PLink-AI (Y-C28) — if you'd rather source the module and carrier separately.
Two caveats worth noting:
- Where a range is conditioned (the Realtimes systems' "-40 to 60 °C is specified at 140W consumption", and MILBOX-THR's range "depends on SKU or module"), the -40 °C rating holds only under that condition — confirm your exact configuration with the maker before committing.
- I could not verify whether the Jetson T5000/T4000 modules themselves are rated to -40 °C in any ambient sense from these results; the module-level figures I found are thermal-design limits (TTP/junction), which are not operating-environment ratings, so I'm not presenting them as such.
