Summary

The Sparkfun CANBus, Micro SD and Joystick Shield combines Controller Area Network communication, data storage, and user input capabilities with LED status indicators in a comprehensive interface shield.

Description

This multifunctional shield integrates CAN bus communication for automotive/industrial applications, micro SD card storage for data logging, a joystick for user input, and status LEDs for visual feedback. The CAN bus interface supports configurable speeds and operational modes, while the micro SD card provides reliable data storage. The analog joystick offers directional input with press functionality, and two LEDs serve as status indicators. Ideal for complex systems requiring communication, data recording, and user interaction.
