ESP32 CAM Module with OV3660 Camera Module

The ESP32-CAM with OV3660 is an enhanced camera development board featuring a higher-resolution 3-megapixel camera sensor while maintaining the same powerful ESP32 WiFi and Bluetooth connectivity platform. With the upgraded OV3660 camera module capable of capturing images at resolutions up to 2048×1536 pixels, this board delivers superior image quality for applications requiring detailed photography, higher-resolution surveillance, or advanced computer vision tasks.

The OV3660 3-megapixel sensor provides significantly better image clarity and detail compared to the standard 2MP OV2640 variant, making it ideal for license plate recognition, facial detection systems, quality inspection applications, and any project where image resolution matters. The onboard microSD card slot supports local storage of high-resolution images and videos, while the ESP32’s dual-core processor efficiently handles the increased data throughput from the higher-resolution sensor.

Powered by the ESP32-WROOM-32 module with integrated 802.11 b/g/n WiFi and Bluetooth 4.2, this board enables seamless wireless image transmission and remote camera control. The compact design and exposed GPIO pins provide flexibility for adding external sensors, displays, or control interfaces. Compatible with Arduino IDE and ESP-IDF development frameworks with extensive library support for camera control and image processing. Perfect for high-resolution security cameras, advanced smart doorbells, document scanning applications, industrial inspection systems, and AI-powered image recognition projects requiring superior image quality.

Note: This module does NOT have a built-in USB-to-serial converter. Programming requires an external USB-to-TTL adapter (FTDI or CH340) or an ESP32-CAM-MB programmer board (sold separately).
