Boson Cookie I/O Expansion Shield for Arduino

The Boson Cookie I/O Expansion Shield for Arduino is a compact interface board designed to simplify prototyping and peripheral connections on Arduino microcontrollers. It provides plug-and-play access to a range of sensors and actuators, making it well suited for students, educators, and hobbyists. Its straightforward layout eliminates messy breadboarding for robotics and coding projects.

Compact shield design

The board mounts directly onto your Arduino to expand available interface pins while keeping the overall footprint small. This compact layout makes it suitable for portable projects and tidy classroom setups.

PH2.0 and Gravity compatibility

Equipped with PH2.0 ports, the shield offers direct compatibility with Gravity ecosystem modules. This allows users to connect sensors, inputs, and outputs quickly without loose jumper wires.

Switchable 3.3V and 5V power

An onboard power switch lets you toggle operating voltage between 3.3V and 5V. This ensures broad compatibility with standard 5V components as well as sensitive 3.3V peripherals.

Dedicated digital and analog pins

The shield routes Arduino digital and analog channels into standardised connector blocks. This layout speeds up wiring for analog sensors, digital switches, and signal lines.

Dual I2C interface ports

Two dedicated I2C headers allow you to hook up multiple I2C-compatible devices such as screens and sensor arrays simultaneously. This simplifies communication across shared data buses.
