## Summary description

PIMORONI Pico Omnibus is a dual I/O expansion board designed for Raspberry Pi Pico. It provides additional GPIO access and breakout connectivity to extend the Pico’s input/output options for prototyping, sensor integration, and small electronics projects. The module mounts directly onto the Pico and offers convenient routing of signals for hobbyist and development use.

## Long description

PIMORONI Pico Omnibus dual I/O expander for Raspberry Pi Pico is an add-on expansion HAT designed to increase the input/output options of a Raspberry Pi Pico. The board mounts directly onto the Pico and exposes additional GPIO lines and breakout connectivity, allowing easy connection of sensors, actuators and peripheral modules. Its compact footprint and straightforward pin routing are intended for rapid prototyping and small electronics projects where extra signal access is required.
Advantages
The dual I/O expander provides a simple, space-saving way to access more GPIO without complex wiring. It offers clear breakout points for reliable signal routing and is compatible with the Pico form factor for stable mechanical and electrical connection. The design reduces the need for breadboard jumpers and simplifies integration of multiple sensors or devices into a single development setup.
Suitable for
Rapid prototyping with Raspberry Pi Pico
Connecting multiple sensors and small actuators
Educational electronics and hobby projects
Compact embedded development and testing
Signal breakout for breadboard-free setups
Key specifications
Form factor: mounts directly onto Raspberry Pi Pico
Connectivity: dual I/O expansion with multiple breakout pins
Compatible signals: general-purpose I/O lines for digital input/output
Mechanical: compact PCB designed for stable Pico attachment
Intended use: prototyping, sensor interfacing and small electronics projects
How to use
Attach the Pico Omnibus directly to the Raspberry Pi Pico header so that the pins align securely. Once mounted, access the exposed breakout pins to connect sensors, switches, LEDs, motors or other peripherals using short jumper leads or soldered connections as appropriate. Configure the Pico’s software to use the additional GPIO lines for input or output, following the Pico SDK or MicroPython pin mapping. Verify connections and power requirements before applying power to avoid short circuits or incorrect wiring.
Usage recommendations
Use short, well-insulated jumper wires for temporary connections and consider soldering headers for longer-term projects. Check signal voltage compatibility of attached devices with the Raspberry Pi Pico and implement appropriate level shifting if needed. For stable mechanical setups, secure the Pico and expansion board within a protective enclosure to prevent accidental disconnection during testing.
