Description and specs

We are no longer producing this version of the OpenMV Cam. However, we'll keep the product webpage up for documentation purposes.

See our successor to the OpenMV Cam M4 V1, the OpenMV Cam RT here.


The OpenMV Cam is a small, low power, microcontroller board which allows you to easily implement applications using machine vision in the real-world. You program the OpenMV Cam in high level Python scripts (courtesy of the MicroPython Operating System) instead of C/C++. This makes it easier to deal with the complex outputs of machine vision algorithms and working with high level data structures. But, you still have total control over your OpenMV Cam and its I/O pins in Python. You can easily trigger taking pictures and video on external events or execute machine vision algorithms to figure out how to control your I/O pins.

The OpenMV Cam features:

  • The STM32F427VG ARM Cortex M4 processor running at 180 MHz with 256KB of RAM and 1 MB 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 μSD Card socket capable of 100Mbs reads/writes which allows your OpenMV Cam to record video and easy pull machine vision assets off of the μSD card.
    • A SPI bus that can run up to 45Mbs 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 9 I/O pins on the board).
    • And, an RGB LED and two high power 850nm IR LEDs.
  • The OV2640 image sensor is capable of taking 320x240 8-bit Grayscale images or 320x240 16-bit RGB565 images at 20 FPS. Most simple algorithms will run between 20-40 FPS on QQVGA (320x240) resolutions and below. Your OpenMV Cam comes with a 2.8mm lens on a standard M12 lens mount. If you want to use more specialized lenses with your OpenMV Cam you can easily buy and attach them yourself.
