Summary

The Keyestudio CANBus and Micro SD Shield provides Controller Area Network (CAN) bus communication and micro SD card storage capabilities for automotive and industrial data logging applications.

Description

This shield combines CAN bus interface functionality with micro SD card storage, enabling both real-time communication with automotive/industrial systems and data logging capabilities. The CAN bus interface supports configurable bus speeds, listen-only mode, loopback testing, and message prioritization. The micro SD card interface allows for storing CAN bus messages, system logs, or other data with timestamp information. Ideal for automotive diagnostics, industrial monitoring, and any application requiring robust communication with data recording.
