From the project

STM32 Nucleo-64 Development Shield to connect NXP TJA1443 CANbus chip with some memory and GPS probe interface

STM32 Nucleo-64 Development Shield to connect NXP TJA1443 CANbus chip with some memory and GPS probe interface.

The main purpose of this project is to utilize the full potential of the NXP TJA1443 chip in a CAN-FD network. By integrating this chip with the Nucleo-32G0B1, we aim to develop and test various protocols within the CAN network, providing a robust platform for CAN-FD communication.
