NUCLEO-G474RE compatible CAN shield.

README

CAN-Shield for NUCLEO-G474RE

NUCLEO-G474RE compatible CAN shield, which is our main microcontroller for the battery management system (BMS/AMS).

Overview

Acts as can transciever for the BMS. Has two 12V output pins, one in case of a BMS fault. The other to set the state (on/off) of the HV charger.

CAN 1 is designated for the communication with FSGs datalogger, because of the high 1Mbit CAN baudrate.

CAN 2 is designated to communicate with the rest of the car, at a lower baudrate.

Compatible to the Analog Devices EVAL-ADBMS6822 board, can be directly slotted onto the nucleo board at the same time.

WR-TBL 3.5mm Connectors for signals to and from the board.
