The Hardware:

The Software:

OpenMV uses a lot of cool open-source software including MicroPython, ChaN's FatFS, ARM's DSP/Math libraries etc.. And it's completely programmable in Python 3! OpenMV can run Python scripts that have access to peripherals (SPI/I2C/UART, CAN, PWM, ADC and DAC), uSD filesystem, wireless, and the image processing library.

The IDE:

OpenMV includes a cross-platform IDE (based on Qt Creator) designed specifically to support programmable cameras. The IDE allows viewing the camera's frame buffer, accessing sensor controls, uploading scripts to the camera via serial over USB (or WiFi/BLE if available) and includes a set of image processing tools to generate tags, thresholds, keypoints etc..

OpenMV 1, 2 and 3:

The OpenMV1 was based on STM32F4 running at 168MHz with very small RAM and Flash. The main advantage of OpenMV1 was small form factor (1.0" x 1.3").  OpenMV2 used the newer STM32F429 runing at 180MHz, with more built-in SRAM, external 16MB SDRAM, external lens for the sensor, 2xIR LEDs, 2xServo headers and 20 I/Os. Finally, OpenMV3 uses the latest Cortex-M7 and is currently in production (see full specs below).
