OV2640 2MP Camera with built-in flash LED (also supports OV7670)
Dual-Core Xtensa LX6 up to 240 MHz, 600 DMIPS
520 KB SRAM + 4 MB PSRAM for image buffering and processing
4 MB SPI Flash for firmware storage
Wi-Fi 802.11 b/g/n/e/i — STA / AP / STA+AP modes
Bluetooth 4.2 + BLE built-in
IPEX connector + onboard PCB antenna
MicroSD card slot for local image and video storage
9 GPIO pins — UART, SPI, I2C, PWM, ADC, DAC
Multiple sleep modes for battery-powered deployments
OTA firmware updates (FOTA) and Smart Config / AirKiss provisioning
Embedded Lwip and FreeRTOS

Common Applications

Live Wi-Fi video streaming (MJPEG / JPEG)
Face detection and recognition (using ESP-WHO framework)
QR code and barcode scanning
Home security cameras and doorbell cameras
Time-lapse photography and wildlife monitoring
Smart attendance systems with facial recognition
IoT image capture and cloud upload
Industrial wireless visual inspection

Flashing Guide

The ESP32-CAM does not have a built-in USB port. You need a USB-to-TTL adapter (CP2102, 5-pin) to flash firmware.

Connect IO0 to GND before powering on to enter flash mode
Upload your sketch via Arduino IDE or ESP-IDF
Disconnect IO0 from GND and reset to run the uploaded firmware
In Arduino IDE: install Espressif ESP32 board package, select AI-Thinker ESP32-CAM

Development Environment Support

Arduino IDE — AI-Thinker ESP32-CAM preset via Espressif board package
ESP-IDF — Full Espressif IoT Development Framework support
MicroPython — Community firmware builds available
PlatformIO — VS Code extension, native ESP32-CAM support

Package Contents

1 x ESP32-CAM WiFi Bluetooth Development Board with OV2640 Camera Module

QnA

Q: Do I need a programmer to use the ESP32-CAM?
Yes. The ESP32-CAM has no built-in USB port. You need a CP2102 (5-pin) USB-to-TTL adapter to flash firmware. Connect IO0 to GND before powering on to enter flash mode.

Q: Can I power it via the GPIO pins?
Yes. Supply 5V to the 5V pin or 3.3V to the 3.3V pin. Ensure your power source can provide at least 500mA as the board draws significant current during Wi-Fi transmission.

Q: What is the maximum camera resolution?
The OV2640 supports up to 1600x1200 (UXGA / 2MP) for still images. For video streaming, typical resolutions are 640x480 (VGA) or 320x240 (QVGA) for smooth frame rates over Wi-Fi.

Q: Can I use a microSD card with it?
Yes. The board has a microSD card slot (TF card). Note that when the microSD card is in use, several GPIO pins are occupied by the SPI interface, limiting available I/O.

Q: Is it compatible with Arduino IDE?
Yes. Install the Espressif ESP32 board package in Arduino IDE (v1.8+ or v2.x), then select AI-Thinker ESP32-CAM from the board list. Many example sketches including CameraWebServer are available out of the box.
