Gravity: Arduino Shield for Raspberry Pi B+/2B/3B/3B+/4B
We have ✅ 13 available of the DF-DFR0327 in our Sydney warehouse. An extra 43 units available with a short lead time.
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.
