Arduino Expansion Shield for Raspberry Pi model B

The Arduino Expansion Shield for Raspberry Pi bridges the gap between the Raspberry Pi and Arduino ecosystems. It sits on top of a Raspberry Pi Model B and provides an ATmega32U4 microcontroller (Arduino Leonardo compatible) with full Arduino-compatible pin mapping, allowing you to use standard Arduino shields and hundreds of sensors directly with your Pi.

The Pi handles computing-intensive tasks like image processing, wireless communication, and complex algorithms, while the ATmega32U4 handles real-time I/O tasks like motor driving and fast sensor responses. Together, they give your project both a powerful "brain" and a responsive "cerebellum".

Key Features

• ATmega32U4 Microcontroller – Arduino Leonardo compatible with full Arduino pin mapping
• Arduino Shield Compatible Layout – Stack standard Arduino shields directly onto your Raspberry Pi
• XBee Socket – Compatible with BLE Link (BT4.0), Bluetooth Bee (BT2.1), and XBee modules
• DS1307 RTC Module – Keeps time even when power is off or battery is removed
• Bidirectional Logic Converter – Converts Raspberry Pi GPIO signals between 3.3V and 5V
• 3-Pin Sensor Headers – For both Arduino pins and Pi GPIO, directly compatible with DFRobot Gravity sensors
• Extended Pi Interfaces – 8 GPIO pins plus SPI, I2C, and UART ports broken out with standard headers
• Dimensions – 88 × 56 × 17 mm

Ideal For

• Robotics projects combining Pi vision with Arduino motor control
• IoT systems needing both real-time response and network connectivity
• Expanding a Raspberry Pi with Arduino sensor and shield libraries
• Projects requiring wireless communication via XBee or Bluetooth
