A dual GPIO expander board for the Raspberry Pi Pico that duplicates all GPIO pins into two sets of 2×20 male headers. Plug your Pico into the centre female socket, then connect two expansion modules simultaneously — doubling your prototyping capability without rewiring.
Features clear pinout labels on the front side and an immersion gold finish for reliable connections and a polished look.
Key Features
- Dual GPIO Breakout – Two sets of 2×20 male headers mirroring all Pico pins
- Centre Female Socket – Direct attachment for Raspberry Pi Pico (with male headers soldered)
- Clear Pinout Labels – Printed on the front for easy identification
- Immersion Gold Finish – Durable, low-resistance contacts
- Jumper Wire Compatible – Also usable without directly mounting the Pico
Ideal For
- Connecting multiple Pico expansion boards at once
- Prototyping and testing with simultaneous peripherals
- IC and module testing on the Pico platform
Note: Ensure there are no pin conflicts between modules before connecting them simultaneously. Raspberry Pi Pico and expansion modules are not included.

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.
