DESCRIPTION

INCLUDES

• 1x OpenMV Cam H7 R2
• 2x 8-pin Male Header
• 2x 8-pin Female Stackable Header

FEATURES

• The STM32H743II ARM Cortex M7 processor running at 480 MHz with 32MBs SDRAM + 1MB of SRAM and 32 MB of external flash + 2 MB of internal 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 μSD 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.
  • Two I/O pins for servo control.
  • Interrupts and PWM on all I/O pins (there are 10 I/O pins on the board).
  • And, an RGB LED and two high power 850nm IR LEDs.
  • 32 MB of external 32-bit SDRAM clocked at 100 MHz for 400 MB/s of bandwidth.
  • 32 MB of external quadspi flash clocked at 100 MHz in 4-bit DDR mode for 100 MB/s of bandwidth (read speed).
• A removable camera module system allowing the OpenMV Cam H7 to interface with different sensors:
  • The OpenMV Cam H7 Plus comes with a MT9M114 image sensor is capable of taking 2592x1944 (5MP) images. Most simple algorithms will run between 25-50 FPS on QVGA (320x240) resolutions and below. Your image sensor comes with a 2.8mm lens on a standard M12 lens mount. If you want to use more specialized lenses with your image sensor you can easily buy and attach them yourself.
  • For professional machine vision applications you can buy our Global Shutter Camera Module.
  • For thermal machine vision applications you can buy our FLIR Lepton Adapter Module.
• A LiPo battery connector compatible with 3.7V LiPo batteries commonly sold online for hobbyist robotic applications.
