computer vision

I wrote about Jevois-A33 computer vision camera based on Allwinner A33 quad core Cortex A7 processor last week, and today, I’ve come across OpenMV Cam M7 open source computer vision board based on a much less powerful STMicro STM32F7 ARM Cortex M7 micro-controller, but with the advantage of consuming less power, and exposing some extra I/Os. OpenMV Cam M7 board specifications & features: MCU – STMicro STM32F765VI ARM Cortex M7 @ up to 216 MHz with 512KB RAM, 2 MB flash. External Storage – micro SD slot Camera Omnivision OV7725 image sensor supporting 640×480 8-bit grayscale images or 320×240 16-bit RGB565 images at 30 FPS 2.8mm lens on a standard M12 lens mount USB – 1x micro USB port (Virtual COM Port and a USB Flash Drive) Expansion – 2x 8-pin headers with SPI, I2C CAN bus, asynchronous serial bus (Tx/Rx), 12-bit ADC, 12-bit DAC, 3x I/Os for servo control; interrupts and PWM on […]
