A GPIO expansion board that multiplies a single Raspberry Pi 40-pin GPIO header into three parallel rows. This allows you to stack multiple HATs, breakout boards, or jumper wire connections on the same set of GPIO pins simultaneously.
Key Features
- 1-to-3 GPIO Expansion – Three full 40-pin headers from one GPIO connector
- 40-Pin Compatible – Supports all Raspberry Pi models with 40-pin GPIO
- Stack Multiple Boards – Use HATs, add-ons, and jumper wires at the same time
Specifications
- Dimensions – 73 × 60mm
- Weight – 29.2g
Compatibility
- Raspberry Pi 4 Model B
- Raspberry Pi 3 Model B / B+
- Raspberry Pi 2 Model B
- Raspberry Pi Model B+
Package Contents
- 1× GPIO Expansion Board (1-to-3)
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
