The RS485 CAN HAT will enable your Pi to communicate with other devices stably in long-distance via RS485/CAN functions.
RS485 is one of the most robust wired serial communication protocol that can support distance up to 1200 meters (4000 ft) while CAN (Controller Area Network) is used in automotive that offer high immunity to noise in cars.
