The DFRobot IO Expansion HAT is a professional-grade interface board engineered to expose and organize the native GPIO and communication ports of the Raspberry Pi 5, 4B, and 3B+. It eliminates the need for messy breadboard wiring by providing clearly labeled, screw-terminal-compatible connections for all major signal types, including digital I/O, analog inputs, PWM outputs, and serial buses (I2C, UART, SPI).
Its core design principle is seamless integration with the DFRobot Gravity Series, utilizing the standardized 3-pin or 4-pin connectors to enable plug-and-play functionality with hundreds of compatible sensors, actuators, and displays. The board incorporates robust power management, supplying stable 5V and 3.3V logic levels for connected devices and featuring a separate input for higher-current servo power (6-12V), making it ideal for robotics and multi-servo applications.
