The module converts the logic levels into the differential voltages required by the CAN standard, and vice versa. The IC operates with supply voltages between 3.3 V and 5 V, allowing the board to be connected to both 3.3 V systems and 5 V controller boards without requiring additional level shifters.\u003c\/p\u003e \u003cp\u003eThe breakout board provides connections for a CAN-High and CAN-Low conductor via screw terminals, while the signal lines and power supply are connected via standard pin headers. Differential transmission makes CAN networks resistant to interference, even over distances of 10 meters or more. This enables reliable communication between multiple nodes in larger setups, such as distributed sensor networks in automotive technology, industrial automation, or building control systems.\u003c\/p\u003e \u003cp\u003eThe transceiver requires only a few connecting wires to the controller. CAN networks have an open structure, allowing new modules to be added without interrupting existing wiring.
