It is commonly found on modern machine tools, such as an automotive diagnostic bus.This CANBed M4 is the latest board of the CANBed family, with the ATSAME51G19A MCU and MCP2542FD CAN transceiver to achieve the CAN-FD capability.What is CAN-BUS?CAN stands for Controller Area Network, it is used to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer which allows for control and data acquisition. These devices are also called Electronic Control Units (ECU) and they enable communication between all parts of a vehicle.Today, you can find up to 70 ECUs in a modern car. CAN is a serial communication bus designed for industrial and automotive applications. For example, they are found in vehicles, farming equipment, industrial environments, etc.How does CAN-BUS work?The fuel level, door sensors, odometer, and many more parts of a car have to communicate with each other somehow, and CAN BUS is what they used to do. These CAN-compatible components, which are called “nodes” are connected with a 3-string copper wire, with no central router to govern the flow of data. Every node can hear the messages of every other node.Every node has an ID, where the ones with the higher priority ID can have the priority to “talk” first while the others “listen”. This is to ensure that there are never two nodes talking at the same time. The biggest benefit of CAN-BUS is to be able to just connect components without having to worry about signal routing.Learn more about CAN-BUS [ https://www.seeedstudio.com/blog/2019/11/27/introduction-to-can-bus-and-how-to-use-it-with-arduino/ ] here.ApplicationCar Hacking: easily connect the circuit board to the OBD interface, get the data such as temperature, position, stability of your vehicleEasy building prototype: Powerful ATSAME51G19A 32bit Cortex M4 core helps build various prototypes.SpecificationMCUATSAME51 32bit Cortex M4 coreClock speed120MHzFlash memory512KBRAM192KBEEPROMNo EEPROMInput voltage7~28VInput interfaceSub-D as well as TerminalSize56x41mmHardware Overview1.9x2 IO Pin OUT2.ATSAME51G19A2.
