 **esp32cam** library provides an object oriented API to use OV2640 camera on ESP32 microcontroller.
 It is a wrapper of [esp32-camera library](https://github.com/espressif/esp32-camera).
-This library has been tested with AI Thinker [ESP32-CAM](http://www.ai-thinker.com/pro_view-24.html) board and OV2640 camera.
