We use PiCAN3 hat on our DEATHFISH 2 demo car:

[PiCAN3 CAN Bus HAT for Raspberry Pi 4 with SMPS and RTC (copperhilltech.com)](https://copperhilltech.com/pican3-can-bus-board-for-raspberry-pi-4-with-3a-smps-and-rtc/)

[DEATHFISH 2 - General / Project & Dashboard Showcase - RealDash Forum](https://forum.realdash.net/t/deathfish-2/1377)

Its handy as it can power the RPi from 12v input to the hat.

As for other CAN hats, I believe they all use SocketCAN connection and thus should be compatible with RealDash.
