Prototyping and Engineering Tips from Robogears:

  • Use the 6–12V external power input when driving multiple servo motors to avoid overloading the Raspberry Pi's 5V rail.
  • The onboard STM32 controller provides hardware PWM and 12-bit ADC functionality not available directly on the Raspberry Pi GPIO, making it ideal for analog sensor interfacing.
  • Gravity connectors simplify wiring and reduce connection errors, making this HAT especially suitable for educational and rapid prototyping environments.
  • Compatible with the DFRobot Gravity ecosystem, allowing quick integration with a large range of plug-and-play modules.

Package Includes:

  • 1 × DFRobot IO Expansion HAT for Raspberry Pi 5 / 4B / 3B+ (DFR0566)

Disclaimer:

This expansion board is designed for 3.3V logic-level Raspberry Pi GPIOs. Ensure that connected sensors and peripherals operate within the specified voltage limits. Raspberry Pi board, sensors, jumper wires, and external power supply are not included. Specifications and PCB appearance may vary slightly between production batches without affecting functionality.
