Grove - CAN BUS Module - GD32E103

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.

You can connect it to an XIAO RP2040 with its expansion board and any Grove sensors you need in your CAN Bus project. Seeed Studio have developed more than 400 Grove modules, covering a wide range of applications that can fulfill various needs.

• Grove - 3-Axis Digital Accelerometer(±1.5g) - Sensing data changes for devices' fall detection, monitor if your car is tilted.
• Grove - Multichannel Gas Sensor v2 - Provides a stable and reliable gas detecting function besides Carbon monoxide (CO), Nitrogen dioxide (NO2), Ethyl alcohol(C2H5CH), Volatile Organic Compounds (VOC)
• Grove - Ultrasonic Distance Sensor - To measure the car-to-object distance and provide audible cues and visual aids to the driver for backing up parking, and vehicle proximity awareness 
• Grove - PIR Motion Sensor - To measure infrared light radiating from objects in its field of view
