ESP32 CAM WiFi Module with OV3660 Camera Module 3MP

ESP32-CAM WiFi Module (OV2640 / OV3660)
If you want to build a DIY smart doorbell, a pet monitor, or a basic AI vision system, the ESP32-CAM is the best low-cost way to do it. It combines a powerful dual-core processor with a dedicated camera interface in a package about the size of a matchbox.

Vision & Connectivity:
• Two Camera Options: Depending on your version, you get either the OV2640 (2MP) or the OV3660 (3MP) lens. Both are great for streaming clear video over a local network or capturing snapshots for surveillance.
• Dual-Mode Wireless: It features built-in Wi-Fi and Bluetooth (BLE), so you can upload images directly to a server or control the camera settings from your phone.
• MicroSD Card Slot: The board includes a built-in slot for a MicroSD card, allowing you to record video locally or store thousands of photos without needing a constant internet connection.

Compact & Smart:
• Tiny Footprint: At roughly 40 × 27 mm, it’s small enough to be hidden inside a 3D-printed case or mounted on a small robot.
• AI & Face Recognition: Because it uses the powerful ESP32 chip, it can actually run simple computer vision sketches, like detecting a human face or tracking motion.
• Flash LED: It even has a very bright onboard LED that acts as a flash for taking photos in the dark or as a status indicator.

Best For:
This board is the go-to for smart surveillance, QR code reading, home automation, and AI-based IoT applications. If your project needs to "see" the world, this is the most affordable way to make it happen.
