2 Description

The OpenMV cameras are low-power, Python3 programmable machine vision cameras that support an extensive set of image processing functions and neural networks. OpenMV cameras are programmed using a cross-platform IDE which allows viewing the camera's frame buffer, accessing sensor controls, uploading scripts to the camera via serial over USB (or WiFi/BLE if available). The OpenMV-H7 camera base board is based on the STM32H7 Arm Cortex-M7 MCU operating at 400MHz, and featuring 1MB SRAM, 2MB FLASH, FPU, DSP and a hardware JPEG encoder . The base board has a modular sensor design, decoupling the sensor from the camera. The modular sensor design enables the camera to support multiple sensors including OV7725, MT9V03x global shutter sensor and FLIR Lepton 1, 2 and 3 thermal sensors.
