The SIM800 does not offer any CAN functionality of its own. A CAN connection can, however, be
established between the "Power” port and the "SERIAL, I/O” port for CAN-capable sensors.
Observe the requirements for the design of overcurrent protective devices according to
EN61010, "Technical data", page 24.
