The Pixy2 (CMUcam5) is a smart vision sensor that can be taught to detect objects, track lines, and identify intersections — all at 60 frames per second. It offloads image processing from your microcontroller, sending only the relevant data you need.
Pixy2 uses hue and saturation for detection rather than RGB, making it far more robust against changes in lighting and exposure. It communicates via UART serial, SPI, I2C, digital out, or analogue out, and multiple Pixy2 units can be connected to a single microcontroller.
Key Features
- Teachable Object Detection – Press a button to teach Pixy2 what to recognise
- Line Following – Detects and tracks lines, intersections, and road signs
- 60 FPS Processing – Real-time vision at 60 frames per second
- 7 Colour Signatures – Remember up to 7 different objects simultaneously
- Hue/Saturation Detection – Lighting-independent colour recognition
- Multiple Interfaces – UART, SPI, I2C, digital out, analogue out
- Multi-Unit Support – Connect multiple Pixy2 units to one controller
- Open Source – PixyMon desktop application for configuration and monitoring
Ideal For
- Line-following robots
- Object tracking and sorting
- Arduino and Raspberry Pi vision projects
- Autonomous navigation with road sign detection

Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
