I found 5 Jetson Thor carrier boards whose rated DC input range includes 48 V. That's out of 26 Thor carrier boards I checked.

| Board | Maker | Rated DC input | Room above 48 V |
|---|---|---|---|
| Gauntlet | Connect Tech | 36–60 V | Up to 60 V |
| ARC6N0 T5X | YUAN High-Tech | 20–57 V | Up to 57 V |
| ARC6N0 T5X-8USBC | YUAN High-Tech | 20–57 V | Up to 57 V |
| X241 | Auvidea | 24–48 V | None, 48 V is the limit |
| reComputer J601 Carrier Board | Seeed Studio | 19–48 V | None, 48 V is the limit |
What this means for a truck
- Gauntlet and the two ARC6N0 boards are the only ones rated above 48 V. The bus voltage in a truck may go above its nominal 48 V. If it does, these three give you some margin.
- X241 and reComputer J601 top out at exactly 48 V. Before using either one, check the highest voltage your bus actually reaches.
- Auvidea marks the X241 datasheet as preliminary. auvidea.euauvidea.eu ↗“(preliminary datasheet)”
- Operating temperature might also matter in a vehicle:
- Gauntlet is rated −40 to 85 °C. connecttec...connecttech.com ↗“thermal.min_operating_temp_c=-40”
- The ARC6N0 boards are rated −20 to 45 °C, and only with airflow. yuan.com.twyuan.com.tw ↗“thermal.operating_temp_condition=Requires airflow”
- reComputer J601 is rated −10 to 60 °C. seeedstudi...seeedstudio.com ↗“thermal.min_operating_temp_c=-10”
- I couldn't find an operating temperature for the X241.
What I couldn't confirm
- Surge protection: I couldn't find load-dump or other automotive surge protection, or any automotive certification, for any of these boards. Check the datasheets or ask the makers before installing one in a truck.
- A802 (Leetop): this Thor carrier board has no input voltage listed, so I couldn't tell whether it takes 48 V.
- The other 20 Thor carrier boards have rated maximums below 48 V, from 12 V up to 36 V, so I left them out.
