ESP32 Camera Module
- ESP32 Camera: The ESP32 Camera is a tiny module based on ESP32 chip and OV2640 sensor. You can program it through the ESP-IDF. The board reserved the MPU6050,BME280 and an analog MIC.This module with a IP5306 IC chip so that it can be used with lithium battery (Standard voltage: 3.7V4.2V).
- The camera is CMOS camera, field of View is 78°,best sensor resolution is 1600 * 1200, maximum rms rate is 15fps SXGA.
- OV2640 Sensor’s Parameter:Standard SCCB interface, compatible with I2C interface;Output Formats(8-bit) is YUV(422/420)/YCbCr422; RGB565/555; 8-bit compressed data; 8-/10-bit Raw RGB data; UXGA/SXGA: 15fps; SVGA: 30fps; CIF: 60fps; Scan Mode: Progressive.
- For people: Software / hardware product engineers, designers, project contractors, enthusiasts, start-ups, educational groups amd Maker groups.
