Build Faster with the Expansion Shield IO for Arduino V7.1:Gravity

Expansion Shield IO for Arduino V7.1:Gravity Expansion Shield IO for Arduino V7.1: Gravity makes it easier to connect sensors, servos, wireless modules, and common interfaces without messy jumper wiring.

It is useful when you want a cleaner prototyping layout and faster access to power, signal, and common communication ports.

Why you'll love it

• Gravity-style ports: Fast plug-in wiring for many modules
• 3.3V or 5V selector: Better match for mixed-voltage hardware
• Servo power input: Helpful for motion projects
• Wireless module support: Works with XBee, Bluetooth, APC220, and more
• Arduino Due friendly: Broader board support
• Color-coded connectors: Easier port identification

What you can build

This board is a good fit for learning, prototyping, robotics, and controller-based builds. Use it as the main brain for sensors, displays, wireless projects, and classroom or workshop demos.

Starter bundles

A solid starter setup includes a USB cable, breadboard, jumper wires, and a few DFRobot Gravity sensors or an LCD module for quick testing.

Recommended add-ons

Useful add-ons include sensors, displays, shields, breadboards, headers, and enclosures if you are building a complete prototype or classroom kit.

Technical specifications

Pinout & usage notes

Check the supported input voltage before wiring so the module matches your controller and power source. Use the correct SDA and SCL pins on your controller and make sure the bus voltage is compatible. If you are using Gravity connectors, align the plug correctly and avoid forcing the cable into the wrong header.
