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 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.
