Gravity: Nano I/O Shield for Arduino Nano

Gravity: Nano I/O Shield for Arduino Nano is an expansion board designed to simplify wiring, power distribution, and sensor connection for Arduino Nano and DFRduino Nano microcontrollers. The shield adopts the same form factor as Arduino UNO and arduino Leonardo, making the layout familiar for rapid prototyping. With Gravity interfaces, expanded I2C pins, jumper-wire compatibility, and independent power supply support for servos and sensors, this Nano expansion shield provides a convenient bridge between compact Nano boards and plug-and-play electronic modules.

Gravity Interface for Faster Sensor Connection

This Nano sensor shield adopts the Gravity interface structure, where each pinout includes 5V and GND pins for easier connection to Gravity sensors, servos, and other compatible modules. The wiring-friendly interface helps reduce messy jumper connections when building Nano-based projects. For broader compatibility, the Arduino Nano expansion board also supports standard jumper wires, making the shield suitable for both plug-and-play Gravity prototyping and traditional breadboard-style experiments.

Multiple Power Input Options and Independent Servo Power

The Nano I/O shield provides several power input options and includes independent power supply support for servos and other external sensors that may require extra current. This design helps separate board logic power from higher-load modules, improving the practicality of Nano-based control projects involving motors, servos, or multiple connected sensors. The fully assembled shield provides a more stable and organized hardware base for quick testing, robotics control, and interactive electronics development.

Expanded Interfaces for Wireless and I2C Projects

The board includes dedicated space for the DFRobot bluetooth module and ACP220, making wireless communication expansion easier in compact Arduino Nano projects. Several I2C pins are also expanded for connecting compatible I2C modules. Version 1.1 adds an I2C interface switch, improving compatibility with Arduino Nano, DFRduino Nano V4, and Bluno Nano. This Nano prototyping shield supports multiple controller choices while keeping interface access clear and convenient.

Compatible Nano Microcontrollers

Typical applications include Arduino Nano sensor expansion, Gravity module prototyping, servo control, wireless communication testing, I2C device connection, compact robotics control, classroom electronics experiments, and rapid hardware prototyping. This expansion board is especially suitable for projects that need a cleaner interface layout than direct Nano wiring while keeping the compact Nano development format.
