Abstract

A circuit, method and device for addressing CAN nodes are provided. The circuit includes: a fuse adapter board including a short-circuited circuit; a first CMU including a first MCU and a first CAN identification circuit; and a second CMU including a second MCU and a second CAN identification circuit. The fuse adapter board is connected to the first MCU or the second MCU through the short-circuited circuit, and is configured to control the short-circuited circuit to be shorted to enable a level on a GPIO pin of the first MCU or the second MCU connected to the short-circuited circuit to be a low level, so that the first MCU and the second MCU set their respective CAN addressing based on the respective levels of the respective GPIO pins.
