Raspberry Pi 40 Pin GPIO Expansion Board

Overview

The Raspberry Pi 40 Pin GPIO Expansion Board makes it easy to access and organize every pin on the Raspberry Pi 40-pin header. Designed for makers, educators, and engineers, this GPIO breakout improves wiring speed and reliability for prototyping, IoT, robotics, and embedded projects.

Key Features

• Full 40-pin breakout: Every GPIO pin plus power and ground are broken out to clear, accessible pads.
• Clear labeling: Each pin is labeled to minimize errors and speed up wiring and debugging.
• Breadboard-friendly: Includes a ribbon cable and T-style adapter for direct breadboard integration and tidy test setups.
• Compact and durable: Space-saving design built from quality materials for dependable, long-term connections.
• Prototyping-ready: Ideal for connecting sensors, actuators, LEDs, motors, displays, HATs, and other modules.

Compatibility

This GPIO expansion board is fully compatible with Raspberry Pi models that use the standard 40-pin GPIO header, including Raspberry Pi 4, Raspberry Pi 3, and Raspberry Pi Zero series. It supports standard GPIO signals, 3.3V logic, and the board does not provide level shifting or power regulation.

Whats Included

• 1 x 40 Pin GPIO Expansion Board
• 1 x Ribbon cable for header connection
• 1 x T-style adapter for breadboard mounting

Typical Applications

• Rapid prototyping and circuit testing
• IoT device development and sensor integration
• Educational labs, workshops, and student builds
• Hobbyist robotics, automation, and maker projects

Quick Start

1. Power down your Raspberry Pi and attach the ribbon cable to the 40-pin GPIO header following the pin 1 marker.
2. Connect the other end of the ribbon cable to the expansion board and secure the T-style adapter if using a breadboard.
3. Double-check pin labels before wiring sensors or modules to avoid misconnection.
4. Power on the Raspberry Pi and verify connections in software as needed.

Why Choose This GPIO Expansion Board?

This expansion board removes the tedium and uncertainty of direct header wiring by presenting all 40 GPIO pins in a clear, accessible format. Its breadboard-friendly design and included accessories make it a practical choice for anyone who needs to build, test, or iterate on Raspberry Pi hardware quickly. Use it to speed up development cycles, reduce wiring mistakes, and create cleaner, more reliable prototypes.
