OpenMV Cam H7 - MicroPython Embedded Vision + Machine Learning

The OpenMV Cam H7 is a compact, MicroPython-programmable camera board designed for embedded machine vision and machine learning. Track colours, detect faces, read barcodes, and more — then use the results to control I/O pins in the real world, all without writing C/C++.

Powered by the STM32H743VI ARM Cortex-M7 running at 480 MHz with 1 MB of RAM and 2 MB of flash, the OpenMV Cam H7 has the processing power to run complex vision algorithms at high frame rates. The included OV7725 image sensor captures up to 640×480 at 60 FPS (120 FPS below 320×240) and uses a standard M12 lens mount for easy lens swaps.
