DFRobot DFR0833 OpenMV Cam H7 Plus

DFRobot DFR0833 OpenMV Cam H7 Plus is a small and low-power microcontroller board to implement applications using machine vision in the real world. This cam is programmed in high-level Python scripts. This makes it easier to deal with the complex outputs of machine vision algorithms and working with high-level data structures. The OpenMV cam comes with a built-in Remote Python/Procedure Call (RPC) library. This makes it easy to connect it to a computer, an SBC like the Raspberry Pi or Beaglebone, and a microcontroller like the Arduino or ESP8266/32. The OpenMV cam operates at -20°C to 70°C temperature range and 5V input voltage. Typical applications include line detection, circle detection, rectangle detection, template matching, image capture, video recording, color tracking, marker tracking, face detection, eye-tracking, and person detection.
