The Grove - CAN BUS Module based on GD32E103 delivers high-performance CAN FD communication capabilities in a compact form factor. This module features the GD32E103 microcontroller running at frequencies up to 120MHz, with flash memory ranging from 64KB to 128KB and SRAM from 20KB to 32KB. It implements CAN FD protocol supporting data rates up to 5Mb/s, providing five times faster communication than classic CAN while maintaining compatibility with existing CAN networks. The module simplifies integration through AT command support, enabling straightforward serial port programming at UART baud rates up to 115200. Measuring just 0.79 inches x 1.57 inches x 0.39 inches, it includes a 4-pin Grove connector for seamless plug-and-play connectivity within the Grove ecosystem and Arduino-compatible projects. TX and RX LED indicators provide visual feedback for communication status. Operating at 3.3V, this module is ideal for automotive networks, industrial automation, and embedded systems requiring reliable, high-speed CAN communication in a space-efficient design.
