No — YUAN High-Tech does not have a Thor carrier board rated to -40 °C in our catalog. Their three Thor carrier boards are rated to -25 °C at best:
| Product | Min Operating Temp | Condition |
|---|---|---|
| EDG6N0-S T5X MB | -25 °C | Requires airflow |
| ARC6N0 T5X | -20 °C | Requires airflow |
| ARC6N0 T5X-8USBC | -20 °C | Requires airflow |
Details:
- EDG6N0-S T5X MB — the bare main/carrier board of the EDG6N0-S T5X for Jetson Thor T5000/T4000, rated from -25 °C to 45 °C . Note it is -25 °C, not -40 °C, and the range holds only with airflow. yuan.com.tw +1yuan.com.tw ↗“thermal.min_operating_temp_c=-25 °C”yuan.com.tw ↗“Requires airflow”
- ARC6N0 T5X — 100x130 mm carrier board with daughter board for Jetson Thor T5000/T4000, rated from -20 °C to 45 °C, requires airflow . yuan.com.tw +1yuan.com.tw ↗“thermal.min_operating_temp_c=-20 °C”yuan.com.tw ↗“Requires airflow”
- ARC6N0 T5X-8USBC — ARC6N0 variant with a daughter board adding 8x USB3.2 Gen2 Type-C, also rated from -20 °C to 45 °C, requires airflow . yuan.com.tw +1yuan.com.tw ↗“thermal.min_operating_temp_c=-20 °C”yuan.com.tw ↗“Requires airflow”
So if -40 °C is a hard requirement, none of YUAN High-Tech's Thor carrier boards meets it. I did not find any YUAN High-Tech Thor carrier board with a -40 °C rating, and I couldn't determine whether they offer such a product outside our catalog. If you'd like, I can check other partner vendors' Thor carrier boards for -40 °C-rated options.
