MU Vision Recognition Sensor

SKU: SEN0314

The MU Vision Sensor integrates a built-in deep-learning engine and a wide-angle 30W lens, enabling onboard image recognition without cloud processing. It supports multiple vision algorithms—including color detection, object localization, face/human detection, ball tracking, and card recognition—allowing robots to perceive their environment and respond autonomously. The module provides UART, I²C, and WiFi communication through a Gravity interface, and supports direct configuration and firmware updates via its onboard USB serial port. Compact in size and compatible with Arduino, micro:bit, and Mind+ graphical programming, the MU Vision Sensor is easy to integrate into educational, robotic, and embedded applications.
