Open MV3 Cam M7 intelligent camera
openMV camera is a board with character of small size ,low energy consumption, lost cost . It helps you to complete the robot vision application easily by micropython. The advanced data structure enables you deal with complex output in machine vision algorithm . You can easily use an external terminal to trigger shoot or perform an algorithm. The structure of the algorithm can also be used to control IO pins.
