Grove CAN BUS Module (GD32E103,CAN FD)

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 (5Mbit/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 120MHz. It has a flash size from 64KB to 128KB and an SRAM size from 20KB to 32KB. However, it can not be used as an MCU yet, and this feature will be implemented soon in the future.

If you want to send the CANBus data through Long Range, please refer to the Wio-E5 CAN Dev kit which supports CAN FD, CAN2.0, and RS485 communication and also support the Global Long Range frequency plan with a long-distance transmission range of 10km(ideal value in open area)

Features

• Support CAN communication: Implements CAN FD at up to 5Mb/s
• Easy to program: Support AT command which enables simple serial port programming
• Grove ecosystem: 20mm x40mm x10mm small size, 4pin Grove connector to plug and play, Arduino compatible
