IO Expansion HAT for Raspberry Pi 5 / 4B / 3B+

This IO Expansion HAT from DFRobot enhances the functionality of your Raspberry Pi 5, Raspberry Pi 4B, and Raspberry Pi 3B+. Designed to simplify connectivity, it provides access to all of the Raspberry Pi's IO ports, including digital, analog, PWM, I2C, UART, SPI, and IIS. Its compatibility with the DFRobot Gravity Series means users can focus more on building their projects rather than getting tangled in complex wiring.

The HAT seamlessly integrates with Raspberry Pi GPIO pins, which operate at a 3.3V logic level. For those who need more adaptability, it supports sensors and modules that require either a 5V power supply with 3.3V logic or PWM external power supplies ranging from 6V to 12V. It’s perfect for controlling multiple servos, enabling more sophisticated robotic and automation projects with ease.
