## Summary description

PIMORONI Pico Decker is a GPIO expander / breakout designed for the Raspberry Pi Pico. It provides four groups of accessible I/O lines to simplify wiring and prototyping, exposing Pico pins in a convenient layout for breadboard and header connections. Suitable for development, hardware testing and compact embedded projects where organized pin access is required.

## Long description

PIMORONI Pico Decker is a GPIO expander and breakout board engineered for the Raspberry Pi Pico. It exposes the Pico's pins in a compact, four-group layout that simplifies wiring for breadboard work, header connections and small embedded projects. The board organizes I/O into four separate 4-layer breakout sections so that commonly used signals are easier to reach during prototyping, hardware testing and iterative development.
Advantages
The Pico Decker provides clear, accessible groups of I/O lines that reduce cable clutter and speed up prototyping. Its four-group layout makes it simpler to separate power, ground, digital and analog signals while keeping all Pico pins available. The board's compact footprint and standardized pin spacing support quick connection to breadboards and headers without modifying the Pico itself. Designed for convenience and repeatability, it helps maintain organized wiring during debugging and small-scale deployments.
Suitable for
Breadboard prototyping with Raspberry Pi Pico
Hardware testing and signal breakout
Compact embedded projects requiring organized pin access
Educational electronics and development kits
Key specifications
Form factor: compact breakout board designed specifically for Raspberry Pi Pico
Pin access: four grouped breakout sections exposing Pico I/O lines for easy connection
Layering: quad 4-layer breakout arrangement to separate signal groups
Compatibility: matches Pico pinout and spacing for direct mounting and breadboard use
Use case: intended for prototyping, testing and small embedded applications
How to use
Align the Pico Decker with the Raspberry Pi Pico so the board's pin headers match the Pico pinout, then attach the Pico directly or via compatible headers. Use the four breakout groups to route signals to breadboards, sensors, actuators or measurement equipment. Keep power and ground connections grouped to avoid noise issues, and label wiring during multi-signal tests to simplify troubleshooting. The board does not alter the Pico's operation — it only reorganizes access to the existing I/O lines.
Usage recommendations
For reliable results, secure the Pico and Pico Decker on a stable surface or breadboard and avoid long unshielded jumper wires for high-frequency signals. Group power and ground wiring and, when working with analog inputs or sensitive sensors, minimize electrical noise by keeping signal lines short and separated from high-current traces.
