## Description

The Gravity Arduino Shield for Raspberry Pi brings Arduino-compatible I/O to your Raspberry Pi B+, 2B, 3B, 3B+, or 4B. Built around the ATmega32u4 (Arduino Leonardo), it sits on top of your Pi and gives you access to all standard Arduino shields and sensors alongside the Pi's own GPIO, I2C, SPI, and UART interfaces. This combination lets you leverage the Raspberry Pi's computing power for tasks like image processing, wireless communication, and complex algorithms, while the Arduino handles real-time I/O, motor control, and fast sensor response — the best of both platforms in one stack. Key Features ATmega32u4 Onboard – Arduino Leonardo-compatible microcontroller Full Arduino Pin Compatibility – Works with standard Arduino shields and Gravity sensors 20 Digital I/O + 6 Analog I/O – Full Arduino pin mapping Raspberry Pi GPIO Access – 16 GPIO, I2C, SPI, and UART from the Pi Stackable Design – Mounts directly on the Raspberry Pi's 40-pin header Specifications Microcontroller – ATmega32u4 (Arduino Leonardo) System Voltage – 5V Arduino Digital I/O – 20 Arduino Analog I/O – 6 Raspberry Pi GPIO – 16 Raspberry Pi I2C – 1 Raspberry Pi SPI – 1 Raspberry Pi UART – 1 (TTL) Dimensions – 86 × 61 × 26 mm Compatibility Raspberry Pi Model B+ Raspberry Pi 2 Model B Raspberry Pi 3 Model B / B+ Raspberry Pi 4 Model B Ideal For Combining Arduino real-time I/O with Raspberry Pi computing power Robotics projects requiring motor control and vision IoT projects using Arduino sensors with Pi networking Prototyping with existing Arduino shield libraries Package Contents 1× Arduino Expansion Shield for Raspberry Pi 1× 20 cm Micro-USB Cable 1× CR1220 Button Cell Battery Resources Product Wiki Schematic (PDF) Assembly Drawing (PDF)
