I am using it to control robotics motors. One caveat is that NetworkManager cannot configure CAN interfaces so you have to use systemd-networkd. The two do not always play nicely so you may have to uninstall NetworkManager. systemd-networkd is useful if you want to make configurations persistent, for example setting the buffer size. Otherwise you have to run the configuration commands on every boot.

I bought this CAN expansion to setup RPi as a Companion Computer on my UAV. Works perfectly! On my UAV all actuators/sensors connected to ArduPilot over CAN bus.
