Summary

The Seeed Studio CANBus and Micro SD Shield V2.0 combines Controller Area Network (CAN) bus communication with micro SD card storage, featuring Grove I2C and serial interfaces for comprehensive data logging applications.

Description

This shield integrates CAN bus communication capabilities with micro SD card storage, supporting both real-time data exchange and data logging. The CAN bus interface features configurable bus speeds, dedicated chip select pins, and multiple operational modes including listen-only and loopback testing. The micro SD card interface includes its own chip select pin for independent operation. With Grove I2C and serial interfaces, this shield is ideal for automotive diagnostics, industrial monitoring, and any application requiring both communication and data storage capabilities.
