ESP32-CAM WiFi + bluetooth Camera Module Development Board ESP32 With Camera Module
The ESP32-CAM is a combination pack that is based on the ESP32. This is the successor of the ESP8266, a system on a chip micro-controller developed by Espressif Systems that is loved by many for embedded applications. Why? This is simple: it is very cheap but sufficient processing power. Next to that, it comes with WiFi and Bluetooth embedded. The ESP32-CAM is a variation of the the ESP31 that comes with the OV2640 camera module. This is an 1/4-inch CMOS UXGA (1632*1232) image sensor.

– Supports secondary development
The OV2640 camera module for the ESP32-CAM
1. The OV2640 is a 1/4-inch CMOS UXGA (1632*1232) image sensor that comes with the ESP32-CAM pack. The sensor’s small size and low operating voltage provide all the features of a single UXGA camera and image processor.
2. Through the SCCB bus control, it can output 8/10-bit image data of various resolutions such as full frame, sub-sampling, zooming and windowing. The UXGA image of this product can reach up to 15 frames per second (up to 30 frames for SVGA and 60 frames for CIF). Users have complete control over image quality, data format and transmission.
3. All image processing functions including gamma curve, white balance, contrast, chroma, etc. so can be programmed via the SCCB interface. Image Sensors use unique sensor technology to improve image quality and reduce sharp and stable color images by reducing or eliminating optical or electronic defects such as fixed pattern noise, smearing, and floating.
