ESP32-CAM Module : Camera Module with Wi‑F & SD Card Slot

Introduction

The ESP32-CAM module is a small and inexpensive development board that brings together a powerful ESP32-S microcontroller, a 2MP OV2640 camera, Wi-Fi capability, and an SD card slot.
With this device, users can capture images in real-time, stream videos, and send data wirelessly without the need for a separate device.

This module is a great fit for IoT, home automation, and AI-vision initiatives, as it allows the creation of smart cameras, security systems, and image recognition applications with very few hardware components.
