Four robot controllers are rated down to -20 °C and have CAN bus. All four are rated for that range only with airflow, so plan for that if you install one in an enclosure on an outdoor machine.

How they differ for an outdoor machine:
- The JHCTECH BRAV-7121 is the only fanless option. It's marketed for intelligent robotics and as the controller for agricultural spraying drones. It also lists 5G cellular and a vibration rating of 5 grms, 5–500 Hz, with SSD storage. jhc-techno... +2jhc-technology.com ↗“marketed for intelligent robotics and as the controller for agricultural spraying drones”jhc-technology.com ↗“connectivity.cellular=5G”jhc-technology.com ↗“vibration_rating=5grms/5~500Hz/random/in working (SSD)”
- The JHCTECH BRAV-7131 also lists 5G, and adds 5 Ethernet ports, 4 COM ports and 16 digital I/O channels.

- The Lambortech ECM410-Thor is a functional safety AI platform. Both Lambortech units list GNSS/GPS and a built-in IMU and magnetometer, which may be useful for outdoor navigation. Their upper temperature limit is lower, at 45 °C. lambortech... +3lambortech.com ↗“functional safety AI platform for robotics built on the NVIDIA IGX Thor T5000 module”lambortech.com ↗“connectivity.gnss_gps=True”lambortech.com ↗“connectivity.gnss_gps=True”lambortech.com ↗“an integrated IMU and magnetometer”
Limits of this list:
- None of the four has an IP (dust and water) rating listed in the catalog. Check the manufacturer's datasheet before mounting one where it's exposed to the weather.
- Some other robot controllers don't have a minimum operating temperature or CAN support listed in the catalog, so I couldn't include them. Some might still meet your needs. lambortech...lambortech.com ↗“5 matched, 7 unset”
