Product description
This CAN bus converter converts serial communication from the SPI standard to the CAN protocol. The MCP2515 IC handles protocol conversion, while the TJA1050 transceiver buffers the voltage levels between the microcontroller and the CAN line. The module operates at 5 V and requires just four signal lines (clock, data in, data out, chip select) for the SPI connection.
The CAN bus is suitable for systems that need to reliably network multiple devices over longer distances. In vehicle projects, the module enables connections to engine control units or sensor networks; in industrial applications, it connects distributed measuring stations or actuator modules. CAN is also used in smart home systems with real-time requirements.
The converter connects to a free SPI port on the microcontroller board. The connection labels on the board indicate the function of each pin. A 5 V power source is sufficient; the two CAN lines (high and low) must also be connected to the corresponding CAN network. Software libraries for popular controllers and development environments are freely available.
Safety notice
Before connecting to CAN networks in vehicles or industrial facilities, check whether a qualified electrician needs to be consulted. The module is intended only for building prototypes and for testing and development purposes. It is not intended for installation in household electrical circuits or for production use.
