ESP32-CAM WiFi Development Board with OV5640 Camera Module for Arduino IoT

Overview

The ESP32-CAM is a compact development board that combines a powerful dual-core ESP32 microcontroller with a camera interface and built-in WiFi, giving you a complete platform for IoT and image capture projects. Whether you are building a wireless surveillance node, a smart home sensor, or a connected camera device, this board delivers the processing power and connectivity you need on a single, affordable module.

With a low-power dual-core 32-bit CPU running up to 240 MHz and up to 600 DMIPS of computing power, the board handles image processing and network tasks smoothly. Built-in WiFi supports STA, AP, and STA+AP working modes, so the module can connect to your network, act as its own access point, or do both at once. Multiple sleep modes help you keep power consumption low in battery-driven deployments.

Available in several configurations, including versions with or without the OV5640 camera and dedicated downloader boards, so you can pick the setup that matches your build. Please select the option you need from the dropdown menu.
