The Arduino Mega 2560 R3 Sensor Shield V2.0 is an expansion board designed to simplify the connection of sensors, servos, relays, and communication modules with the Arduino Mega 2560. It breaks out all Mega I/O pins into clearly labeled 3-pin headers (Signal, VCC, GND), enabling fast prototyping, clean wiring, and reliable connections. This shield is ideal for robotics, automation, IoT systems, and educational projects that require multiple peripherals.
