Expansion Board Raspberry Gravity for Raspberry Pi Pico by DFRobot (DFR-20373)

The Expansion Board Raspberry Gravity for Raspberry Pi Pico by DFRobot is an add-on board that provides a convenient interface to connect Gravity sensors and modules to a Raspberry Pi Pico. Designed as part of the Raspberry Gravity series, this expansion board simplifies wiring and reduces setup time when building prototypes, classroom experiments or hobby electronics projects with the Pico microcontroller.

Advantages

This expansion board offers standardized Gravity connectors that eliminate tedious soldering and manual wiring for many analog and digital sensors. It preserves the Pico’s GPIO accessibility while adding clearly labeled ports for quick plug-and-play connection of modules. The board’s layout and compatibility with common Gravity sensors make it suitable for rapid prototyping and iterative testing, speeding up development cycles for educational and hobby use.

Suitable for

• Educational projects and classroom experiments using Raspberry Pi Pico
• Rapid prototyping of sensor-driven applications
• Hobby electronics and maker projects requiring multiple sensor connections
• Testing and demonstration of analog and digital Gravity modules

Key specifications

• Form factor: expansion/add-on board compatible with Raspberry Pi Pico
• Connectors: multiple Gravity standard sensor ports for analog and digital signals
• Signal types supported: analog inputs and digital I/O (depending on connected sensors)
• Compatibility: designed to interface directly with the Raspberry Pi Pico pinout
• Mounting: stackable/plug-in style for easy attachment to the Pico

How to use

Attach the expansion board to the Raspberry Pi Pico following the Pico pin alignment so the board’s header pins match the Pico’s castellated pads or header pins. Plug Gravity sensors or modules into the labeled Gravity ports on the expansion board. Ensure power and ground connections are correctly assigned and that the Pico is powered from a suitable USB or external supply. Use appropriate libraries or simple GPIO/ADC code on the Pico to read sensor values and control connected modules.

Usage recommendations

Before connecting multiple sensors, verify individual sensor voltage and signal levels to ensure compatibility with the Pico’s 3.3V logic. For classroom or prototyping environments, organize cables and modules to prevent accidental shorting and to simplify debugging. Refer to sensor datasheets and Pico documentation for correct pin assignments and recommended software libraries.
