Description

The DFRobot Gravity Nano IO Shield serves as a dedicated expansion interface for the compact Arduino Nano platform. It translates the Nano’s pinout into a robust, user-friendly Gravity connector system, where each port provides direct access to 5V power, ground, and the signal line. This design eliminates the need for messy breadboard wiring when connecting Gravity-compatible sensors, actuators, or servos.

The shield maintains the same footprint as larger Arduino UNO and Leonardo boards, ensuring compatibility with many existing enclosures and mounting solutions. It features an independent power supply section to deliver extra current for power-hungry components like servos, preventing brownouts on the main microcontroller. The board also expands critical communication lines, including dedicated I2C pins, and provides reserved mounting areas for popular wireless modules like DFRobot’s Bluetooth and APC220, facilitating wireless data transmission projects.

Key Features

  • Gravity interface standardizes connections with integrated 5V, GND, and signal pins.
  • Independent power rail supports high-current devices like servos without taxing the Nano's regulator.
  • Expanded I2C bus pins enable easy daisy-chaining of multiple I2C sensors and displays.
  • Pre-assembled unit with castellated pin headers for secure stacking onto the Nano.
  • Designated mounting footprints for DFRobot Bluetooth and APC220 wireless communication modules.
  • Multiple power input options (VIN, 5V) provide flexibility for different power supplies.
  • Jumper wire-compatible pin rows allow for rapid prototyping alongside Gravity connections.
  • UNO/Leonardo form factor ensures broad compatibility with cases and accessory shields.

Applications

  • Rapid prototyping of sensor networks using Gravity-compatible environmental, motion, or light sensors.
  • Building compact, stackable robotics controllers with integrated servo power management.
  • Creating portable data loggers or wireless sensor nodes with Bluetooth or APC220 modules.
  • Educational electronics projects requiring a clean, organized interface for student-built circuits.
  • Industrial prototyping for condition monitoring systems using Arduino Nano as a compact data acquisition unit.

Frequently Asked Questions

What microcontrollers is this shield compatible with?

This shield is specifically designed for the Arduino Nano and DFRobot's DFRduino Nano microcontrollers. It stacks directly onto the Nano's pin headers. Due to its UNO/Leonardo form factor, it can also be used in enclosures designed for those boards, but the pin mapping is for the Nano footprint.

How does the Gravity interface simplify connections?

Each Gravity port on the shield bundles the signal pin from the Nano with a dedicated 5V power rail and a ground (GND) connection into a single 3-pin connector. This allows plug-and-play connection with hundreds of DFRobot Gravity sensors, actuators, and servos without requiring separate power wiring, reducing clutter and potential wiring errors.

Can I power servos directly from this shield?

Yes. The shield features an independent power supply section. You can supply power via the VIN pin or the 5V pin, and this power is routed directly to the Gravity ports' 5V rails. This separates the servo power draw from the Nano's own voltage regulator, preventing system resets or brownouts when servos move under load.

What wireless modules can be installed on this shield?

The PCB includes designated mounting footprints and pinouts for soldering or plugging in DFRobot's specific Bluetooth module and the APC220 UART RF module. This integrates wireless capability directly onto the stack, saving space and simplifying antenna placement compared to external breakout boards.
