ESP32-CAM WiFi Bluetooth Development Board with OV5640 5MP Camera Module

ESP32-CAM WiFi Bluetooth Development Board with OV5640 5MP Camera

The ESP32-CAM WiFi Bluetooth Development Board with OV5640 5MP Camera is a compact wireless camera module suitable for IoT image capture, remote monitoring, robotics vision, time-lapse photography and embedded camera projects. It combines the ESP32 microcontroller with an upgraded OV5640 5MP camera module, making it a better option than standard ESP32-CAM boards that commonly use 2MP OV2640 camera modules.

The onboard ESP32 supports WiFi and Bluetooth connectivity, allowing the board to be used for wireless image streaming, local image capture, web camera projects and cloud-connected IoT applications. The board also includes external PSRAM, which helps in handling higher-resolution camera frames more efficiently.

The OV5640 camera module supports up to QSXGA 2592 x 1944 pixel image output. This makes the board useful for applications where improved image clarity is required, such as 3D printer monitoring, smart meter image reading experiments, classroom projects, robotics prototypes and general ESP32 camera development.

A built-in TF / microSD card slot is provided for local image storage. The board also includes an onboard white flash LED connected to GPIO 4, which can be used for basic illumination or flash control in supported projects.
