Description
With the OpenMV Cam H7, you'll have a powerful imaging solution featuring the MT9M114 image sensor. Capture stunning images with options for 640x480 8-bit Grayscale or 640x480 8-bit BAYER formats, achieving impressive frame rates of 40 FPS or 80 FPS, depending on the resolution. For resolutions below 320x240, expect most simple algorithms to operate smoothly between 40-80 FPS. The camera comes equipped with a 2.1mm lens on a standard M12 lens mount, providing versatility. Should you desire more specialized lenses, they can be easily purchased and attached to the image sensor for enhanced imaging capabilities.
Features
The STM32H743VI ARM Cortex M7 processor running at 480 MHz with 1MB SRAM and 2MB of flash. All I/O pins output 3.3V and are 5V tolerant. The processor has the following I/O interfaces:
The STM32H743VI ARM Cortex M7 processor running at 480 MHz with 1MB SRAM and 2MB of flash. All I/O pins output 3.3V and are 5V tolerant. The processor has the following I/O interfaces:
- A full speed USB (12Mbs) interface to your computer. Your OpenMV Cam will appear as a Virtual COM Port and a USB Flash Drive when plugged in.
- A uSD Card socket capable of 100Mbs reads/writes which allows your OpenMV Cam to take pictures and easily pull machine vision assets off of the μSD card.
- A SPI bus that can run up to 80Mbs allowing you to easily stream image data off the
- system to either the LCD Shield, the WiFi Shield, or another microcontroller.
- An I2C Bus (up to 1Mb/s), CAN Bus (up to 1Mb/s), and an Asynchronous Serial Bus (TX/RX, up to 7.5Mb/s) for interfacing with other microcontrollers and sensors.
- A 12-bit ADC and a 12-bit DAC.
- Three I/O pins for servo control.
- Interrupts and PWM on all I/O pins (there are 10 I/O pins on the board).
- An RGB LED and two high power 850nm IR LEDs.
