OpenMV N6

The OpenMV N6 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 N6 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 N6 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 N6 features:

• The STM32N6 ARM Cortex-M55 vector accelerated processor capable of up to 8 operations per clock running at 800 MHz (6.4 gigaops) with 64MBs SDRAM + 4.2MB of SRAM and 32 MB of program/storage FLASH. The processor features a 1 GHz NPU offering 600 Gigaops of AI/ML compute for running models - allowing you to run YOLO object detection algorithms onboard at 30 FPS, an Image Signal Processor capable of handling up to 5MP RAW BAYER Camera Modules, GPU for graphics acceleration that can accelerate image scaling and 3D image rotation, and onboard H.264 Encode (up to 1080p) and JPEG Encode/Decode support hardware acceleration. All I/O pins output 3.3V and are 3.3V tolerant. The processor has the following I/O interfaces:
  • A high speed USB-C (480Mbs) interface to your computer. Your OpenMV Cam will appear as a Virtual COM Port and a USB Flash Drive when plugged in.
    • 1.5A current limited.
    • With EMI Filtering and TVS protection.
  • A μSD Card socket capable of 104MB/s reads/writes which allows your OpenMV Cam to take pictures and easily pull machine vision assets off of the μSD card.
    • With EMI Filtering and TVS protection.
  • Two SPI buses that can run up to 100Mb/s allowing you to easily stream image data off the system to either the LCD Shield or another microcontroller.
    • And one I2S Bus for an audio CODEC.
  • An I2C Bus (up to 1Mb/s), an I3C Bus (up to 10 Mb/s), two CAN Buses (up to 8Mb/s), and three Asynchronous Serial Buses (TX/RX, up to 12.5Mb/s) for interfacing with other microcontrollers and sensors.
  • A 12-bit ADC (3.3V Tolerant).
    
  • Three I/O pins for servo control.
  • One I/O pin for frame sync/triggering (or servo control).
  • Two I/O pins for low power wakeup.
    • One shared with a button.
  • Interrupts on all I/O pins (there are 18 I/O pins on the board).
  • An onboard RTC that keeps running when the system is in low-power mode.
    • With 8KB of Backup RAM. 
    • With a dedicated backup battery connection.
  • A user controllable/dimmable RGB LED.
  • A user button.
  • Another RGB LED for Charging, USB Power, VIN Power indication.
  • 64 MB of external 16-bit SDRAM clocked at 200 MHz DDR for 800 MB/s of bandwidth.
  • 32 MB of program/storage octal flash clocked at 200 MHz in 8-bit DDR mode for 400 MB/s of bandwidth (read speed).
  • An IMU (Accelerometer and Gyroscope) centered underneath the camera module.
  • A Mic for recording audio and sound detection/processing.
  • Onboard WiFi (a/b/g/n - 11/54/65 Mb/s) and Bluetooth (v5.1 - BR/EDR/BLE) module with a chip antenna.
    • Option to use a U.FL antenna instead.
  • Onboard 10/100/1000 Mb/s Ethernet
    • Ethernet Jack with PoE support via an external shield.
• A removable camera module system, with support for MIPI CSI and 8-bit parallel, allowing the OpenMV N6 to interface with different sensors:
  • The OpenMV N6 comes with a 120 FPS 1MP Color Global Shutter image sensor. Most simple algorithms will run about 120 FPS on VGA (640x480) resolutions and below. If you want to use more specialized lenses with your image sensor, you can easily buy and attach them yourself.
  • For high resolution or outdoor imaging you can buy the 5MP HDR Camera Module. 
  • For multispectral imaging (thermal + RGB), you can buy the Multispectral Thermal Camera Module.
  • For high-resolution, high-frame rate thermal, you can buy the FLIR® BOSON® Adapter Module.
  • For Event Camera Applications, you can buy the GENX320 Event Camera Module.
• A LiPo battery connector compatible with 3.7V LiPo batteries commonly sold online for hobbyist robotic applications with battery charging support via USB.
  • 500 mA Fast Charge Current
  • With TVS Protection.
  • With ADC for reading the battery voltage.
• An ARM 10-pin JTAG Header Compatible with SEGGER J-Link Devices for debugging and programming.
  • With EMI Filtering and TVS protection.
  • BOOT1 switch for debugging.
• External 5V VIN with reverse supply protection.
  • With TVS Protection.
