OpenMV M7 - module with OV7725 camera

Description

OpenMV M7 is a small PCB with an OV7725 camera and a STM32F765VI ARM microcontroller with a Cortex M7 core. The module allows easy implementations in devices / robots where there is a need for image processing. With the help of the module it is possible to create a program that will detect faces, recognize colors, and read QR codes.

OpenMV M7 uses high-level Python scripts (which work with the MicroPython operating system). Thanks to these scripts, it is possible to create complex algorithms that process images. In addition, the board has digital microcontroller outputs / outputs that can be programmed using Python scripts.

The sample capabilities of the module are shown in the video below:
