Arduino Shield Expansion Board

Arduino Shield Expansion Board – Easy Sensor & Module Connectivity

The Arduino Shield Expansion Board is a versatile add-on board designed to simplify connections between an Arduino Uno and various modules and sensors. Instead of using loose jumper wires, this shield provides dedicated headers that let you plug in devices such as SD cards, Bluetooth modules, OLED displays, GSM modules, analog distance sensors, and even servo motors directly onto the board.

What You Can Connect

This expansion board breaks out a variety of useful interfaces so you can attach peripherals quickly and neatly:

• Power Input Terminal – A 2-pin screw terminal to supply power to the Arduino.
• Digital Headers – Fourteen 3-pin digital connectors for digital sensors and servo motors.
• Analog Headers – Eight 3-pin analog connectors for analog sensors like IR distance sensors.
• Serial Interface – One 4-pin header for serial modules such as GSM and GPS.
• I2C Connector – One 4-pin I2C header for displays and sensors that use I2C communication.
• SD Card Socket – One 6-pin header for SPI-based SD card modules.
• Bluetooth Header – One 6-pin slot for HC-05 or similar Bluetooth modules.
• Radio Module Socket – One 6-pin header for wireless modules like APC220.
