CAN Bus ModulesCAN bus modules are devices that provide a connection to a Controller Area Network (CAN) bus. A CAN bus is a communication network used in automobiles and other systems to allow microcontrollers and devices to communicate with each other. CAN bus modules provide a means of interfacing with a CAN bus and can be used to send and receive data over the network. They are commonly used in applications such as automotive diagnostics, industrial automation, and building automation. CAN bus modules may be stand-alone devices or may be integrated into larger systems, such as embedded computers or controllers. They typically have a microcontroller and CAN transceiver on board, as well as connectors for interfacing with the CAN bus and other devices.
