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 is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine 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 metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
