Dual Pico Add-On Expansion Board

The Pimoroni PIM556 PICO Omnibus Dual Expander is a development board that connects two Pico Packs or Bases to a single Raspberry Pi Pico. It arrives fully assembled with labelled headers and rubber feet, so no soldering is required before use.

Makers needing simultaneous add-on access

This board suits developers who want to run two add-ons at once or route extra GPIO signals to jumper wires and prototype circuits. Builders who only ever use one add-on at a time will not need the extra connectors.

Two add-on landing areas with mirrored male headers

The key specification is the pair of mirrored male header zones that accept two add-ons in parallel. If your project requires only a single add-on connection, this dual layout provides no advantage.

Questions about this item

What physical space does the PIM556 board need for its rubber feet?

Four adhesive rubber feet are included to stabilise the board on a flat surface; simply peel and stick them to the corners of the underside.

How is the PIM556 connected to a Raspberry Pi Pico, and what step is often missed?

Press the Pico onto the labelled female headers; the board arrives 99% assembled so only the rubber feet need fitting — forgetting the feet is the common oversight.

What ongoing maintenance does the PIM556 require after installation?

No scheduled maintenance is needed; the board has no moving parts or consumables, so it simply remains in place while you swap Pico Packs or jumper wires as required.
