Seeed Studio Pixy2 CMUcam5 Smart Vision Sensor

Vision sensor for robotics

The Pixy2 CMUcam5 is a compact smart vision sensor designed for makers and students building autonomous robots or computer-vision projects. It processes images on board at 60 frames per second and can track hundreds of objects or follow lines without burdening the host microcontroller. The sensor learns up to seven colour signatures with a single button press and reports only the data you request. It suits hobbyists who need fast, self-contained object detection for Arduino or Raspberry Pi platforms.

Multi-interface connectivity

The board exposes SPI, I2C, UART, USB and analog or digital outputs so you can wire it directly to almost any microcontroller or single-board computer. A configuration utility runs on Windows, macOS and Linux for firmware updates and parameter tuning. All firmware and hardware documentation are open source under a GNU licence, allowing full customisation of detection algorithms. Builders who require wireless streaming or built-in display outputs will need additional hardware.

On-board processing thermals

Because image processing runs on the integrated microprocessor, the sensor handles detection, line tracking and barcode reading internally while drawing power from the host USB or logic supply. No external cooling is required for typical indoor robotics use. The compact form factor fits tight chassis spaces, though users planning continuous high-frame-rate operation in sealed enclosures should verify thermal margins themselves.
