GPIO Extension Board 1 to 3 (40 Pin GPIO) Module

1-to-3 GPIO Port Expansion: Triples the single 40-pin GPIO header on your Raspberry Pi into three identical parallel 40-pin headers, allowing connection of multiple HATs and sensors simultaneously.

Standard 40-Pin Header Compatibility: Equipped with standard 2.54mm pitch 40-pin male headers that accept standard HATs, ribbon cables, jumper wires, and expansion shields.

Clear Pin Silk-Screen Labeling: Displays pin numbering and bus functions directly next to each set of headers to minimize wiring mistakes and streamline circuit debugging.

Direct Motherboard Mount or Extension Cable Ready: Plugs directly onto the Raspberry Pi GPIO header or connects via a 40-pin extension ribbon cable for flexible enclosure positioning.

Durable Multi-Layer PCB Construction: Engineered on a rigid fiberglass circuit board designed for stable signal routing, mechanical stability, and low electrical crosstalk between connected modules.

PCB Composition: Manufactured on high-density FR4 fiberglass laminate designed to handle continuous plugging and unplugging of expansion boards.

Pin Alignment Precautions: When connecting multiple HATs or headers, ensure even alignment over the pins before applying pressure to prevent pin bending or shorts.

Static Handling Precautions: Standard electrostatic sensitive device (ESD). Hold the board by its outer fiberglass edges and practice proper grounding procedures during assembly.

Power Management Care: Note that all three headers share the host Raspberry Pi's power rails and signal lines. Ensure total current draw across connected devices does not exceed your Pi power supply ratings.

Multi-HAT Solution Pitch: Target developers, educators, and advanced makers who need to run multiple expansion boards simultaneously (such as a display HAT alongside a sensor array or motor driver).

Workstation & Test Bench Essential: Market as an indispensable tool for hardware test benches, prototyping setups, and rapid multi-module debugging.

Recommended Accessories: Cross-sell 40-Pin Rainbow Extension Cables, Brass Standoff Hardware Packs, and Raspberry Pi Power Supplies (5V/3A or 5V/5A) to support multiple attached modules.

Universal Pi Compatibility: Highlight full compatibility across all 40-pin Raspberry Pi models, including the Raspberry Pi 5, 4B, 3B+, 3B, Zero, and Zero 2 W.
