Robust serial bus for automotive and industry
Official spec ↗CAN bus
CAN (Controller Area Network) was created by Bosch in the 1980s to connect a car's electronic control units, and today it is a robust fieldbus found in automotive, machinery, robotics and IIoTITermIIoT (Industrial IoT)IIoT (Industrial IoT) is the application of IoT to industrial environments (manufacturing, energy, logistics), with strict reliability and latency requirements.View profile. It is multi-master and resolves collisions by priority arbitration without losing messages, over a noise-resistant differential twisted pair.
Application protocols such as CANopen (industry/robotics) and J1939 (heavy vehicles) are built on top of CAN. CAN FD extends speed and frame size for modern needs.
