Overview
The ESP32-CAM is a development board designed for IoT and image processing applications. It integrates an ESP32-S microcontroller with dual-core Xtensa® 32-bit LX6 processors running at 240 MHz, making it capable of handling complex tasks efficiently. The board includes 520 KB of SRAM and an additional 4 MB of PSRAM, which are ideal for buffering images or videos. With built-in Wi-Fi (802.11 b/g/n) and Bluetooth 4.2 (BLE), it offers robust wireless connectivity for IoT devices.
Equipped with a 2MP OV2640 camera module, the ESP32-CAM supports multiple image resolutions, including UXGA (1600x1200), SXGA (1280x1024), SVGA (800x600), VGA (640x480), and more. Images can be output in formats such as JPEG, BMP, or RAW. The board also features a microSD card slot supporting up to 4 GB for local storage of images and videos. Its compact size of 27 mm x 40.5 mm and low weight of approximately 8 grams make it suitable for embedded applications.
The ESP32-CAM includes 9 GPIO pins for interfacing with external devices and peripherals, supporting communication protocols like UART, SPI, I2C, and PWM. A built-in PCB antenna or an optional external antenna ensures reliable wireless performance, and the board can be powered via a 5V DC input or a 3.3V pin. It features onboard security with WPA/WPA2 encryption, secure boot, and flash encryption, making it suitable for secure applications.
Ideal for smart cameras, robotics, and AI projects, the ESP32-CAM also supports deep sleep mode, consuming as little as 10 µA for energy-efficient operation. Its programming compatibility with Arduino IDE and Espressif SDK simplifies development. The ESP32-CAM is a cost-effective solution for IoT projects requiring image and video processing, providing excellent performance and flexibility.
