The Grove – CAN BUS Module based on GD32E103 is a compact serial-to-CAN FD interface for Grove projects. It uses a GD32E103 microcontroller with module firmware to bridge UART commands to CAN FD communication, giving makers and embedded developers a simple way to add high-speed CAN networking without building a full CAN interface from scratch.

CAN FD and Serial Control

CAN FD extends classic CAN by increasing the payload data phase, while maintaining classic CAN-style arbitration for compatibility. This module is designed to make that bus available through a serial interface, so a host board can send commands over UART and communicate with CAN FD nodes.

The GD32E103 is used as the module controller for the serial-to-CAN FD firmware. The product information does not present it as a standalone user-programmable MCU.

Applications

• Vehicle data experiments and diagnostic projects
• 3D printer control networks
• Building automation and lighting control systems
• Medical instruments and equipment communication
• Grove sensor projects that need CAN FD connectivity
