CAN-FD Insights

What is CAN-FD?

CAN FD (CAN with Flexible Data-Rate) is an improved version of the classic CAN (Controller Area Network) bus protocol. It allows for higher data rates and larger payloads compared to classic CAN. Common uses include automotive applications for communication between electronic control units (ECUs), as well as in industrial automation and other embedded systems where reliable and fast data transmission is needed.
