Seeed Studio Grove CAN-BUS Module (based on GD32E103)

This Grove CAN-BUS Module based on GD32E103 adopts a brand-new design, uses the cost-effective and high-performance GD32E103 microcontroller as the main control and cooperates with a firmware we wrote to complete the function of the serial port to CAN FD.

Features

• Support CAN communication: Implements CAN FD at up to 5 Mb/s
• Easy to program: Support AT command which enables simple serial port programming
• Grove ecosystem: 20 x 40 x 10 mm small size, 4-pin Grove connector to plug and play, Arduino compatible

This Grove CAN-BUS Module supports CAN FD(CAN with Flexible Data-Rate) communication, which is an extension to the original CAN protocol as specified in ISO 11898-1 that responds to increased bandwidth requirements in automotive networks. In CAN FD, the data rate (i.e. number of bits transmitted per second) is increased to be 5 times faster than the classic CAN (5 Mbit/s for the data payload only, the arbitration bit rate is still limited to 1Mbit/s for compatibility). It supports AT command which enables simple serial port programming.

This Grove CAN-BUS Module is based on GD32E103 with a frequency up to 120 MHz. It has a flash size from 64 KB to 128 KB and an SRAM size from 20 KB to 32 KB.
