## Description

The DFRobot Gravity IO Expansion Shield V7.1 simplifies Arduino prototyping by breaking out all digital and analogue pins into colour-coded 3-pin (Signal, Voltage, Ground) Gravity connectors. Plug in sensors, actuators, and modules directly — no soldering or breadboard wiring required. Version 7.1 adds a 3.3 V/5 V voltage selection jumper for compatibility with boards like the Arduino Due and Raspberry Pi, an external servo power input with protective diode, and a convenient serial switch that lets you program your ATmega328-based boards (such as the Uno) without disconnecting XBee or other serial devices. Key Features Colour-Coded Gravity Connectors – 3-pin headers for all digital and analogue pins, clearly labelled 3.3 V / 5 V Selectable – Jumper-configurable operating voltage for broader board compatibility XBee Socket – On-board socket for XBee, Bluetooth, APC220, and other wireless modules Serial Programming Switch – Toggle between programming mode and serial device communication without rewiring External Servo Power – Dedicated servo power input (4.8–6 V) with protective diode External Power Input – PWR_IN terminal for 7–12 V power supplies On-Board LED and Reset – LED on pin 13 and reset button for convenience Immersion Gold Finish – High-quality PCB surface for reliable connections Specifications Input Voltage – 7–12 V (PWR_IN), 4.8–6 V (SERVO_PWR) Module Voltage – 3.3 V or 5 V (selectable) Supported Interfaces – I2C, SPI, XBee (XBee Pro), Bluetooth, APC220 Compatible Boards – Arduino Uno, Mega, Due, Leonardo, and other standard-footprint boards Ideal For Rapid robotics and IoT prototyping Classroom and workshop environments DFRobot Gravity sensor and actuator projects Wireless communication with XBee or Bluetooth modules Package Contents 1× IO Expansion Shield for Arduino V7.1 Resources Product Wiki Schematic (PDF)
