ESP32-CAM WiFi Bluetooth Camera Development Board with OV2640 and 27x40.5x4.5mm DIP Footprint

The ESP32-CAM camera development board is a compact module that integrates Wi-Fi, Bluetooth, and camera control for IoT hardware terminals. It is built around a small 802.11b/g/n Wi-Fi + BT/BLE SoC module and a low-power dual-core 32-bit CPU that runs at up to 240MHz with up to 600 DMIPS. With a footprint of only 27 x 40.5 x 4.5mm, it fits into space-limited enclosures and supports image upload over Wi-Fi plus TF card storage. The board includes an OV2640 camera module and a built-in flash. It is intended for applications such as home smart devices, industrial wireless control, wireless monitoring, QR wireless identification, and wireless positioning system signals. The DIP package plugs directly into a backplane, which supports fast production and provides a reliable connection method for a variety of IoT hardware terminals. Deep sleep current is a minimum of 6mA, which is relevant for designs that need to manage power carefully.

Features and Construction

The module combines wireless connectivity, camera support, and a range of hardware interfaces in a single board. It is supplied with an OV2640 camera, and the OV7670 camera can be used if purchased separately. The construction is based on a DIP package that plugs directly into a backplane for fast production.

Material and Build

The ESP32-CAM uses a PCB-based construction in a DIP package. This package type allows the module to plug directly into a backplane, which supports fast production and gives customers a reliable connection method for IoT hardware terminals. The board includes a built-in flash and supports both OV2640 and OV7670 cameras, although only the OV2640 camera module is included as standard. The OV7670 camera is available separately if required. The module is designed as a small system with a competitive small form factor.

Size and Practical Fit

The footprint is 27 x 40.5 x 4.5mm, which is small enough for compact IoT devices and camera-based monitoring setups. This size allows the board to be used in space-constrained builds where a larger development board would not fit. The DIP package supports direct mounting into a backplane, which helps with production workflows. The small size also makes it practical for integrating into home smart devices and wireless monitoring products where the camera and wireless module need to be close together.

Uses and Placement

The ESP32-CAM is suitable for a range of IoT applications where a small camera module with Wi-Fi and Bluetooth is needed. It supports image upload over Wi-Fi, TF card storage, and multiple sleep modes, making it adaptable to different power and data requirements. It can be used in both event or professional settings and everyday home setups.

Event or Professional Use

The module can be used in industrial wireless control, wireless monitoring, and wireless positioning system signals. It also supports QR wireless identification, which is useful in professional or event-based systems that need to read codes and upload data. The built-in camera and Wi-Fi upload capability allow images to be sent without a separate camera module. The DIP package and backplane connection method support fast production for hardware terminals used in these environments.

Everyday Home Use

For home smart devices, the ESP32-CAM can be used in wireless monitoring and other IoT applications where a small camera board is required. It supports Wi-Fi and Bluetooth connectivity, so it can communicate with home networks and compatible devices. The TF card slot allows local storage of images, and Wi-Fi upload allows images to be sent to a server or other device. The small 27 x 40.5 x 4.5mm size helps it fit into home setups where space is limited.

Benefits and Buying Value

The board combines camera, Wi-Fi, Bluetooth, and storage support in one module, which reduces the need for separate components in IoT projects. It supports multiple sleep modes and a deep sleep current of at least 6mA, which is relevant for power-sensitive applications. The DIP package and backplane connection method support fast production and reliable connections.

Reuse and Low Maintenance

The module supports serial local upgrades and remote firmware upgrades (FOTA), which allows firmware to be updated without replacing hardware. It also supports STA, AP, and STA + AP working modes, plus Smart Config and AirKiss one-click distribution network. These features help with setup and ongoing use in IoT deployments. The deep sleep current of a minimum of 6mA supports designs that need to reduce power consumption between active periods.

Why Choose This Product

The ESP32-CAM is a compact camera development board with a 27 x 40.5 x 4.5mm footprint, OV2640 camera included, built-in flash, TF card support, and Wi-Fi image upload. It supports UART, SPI, I2C, PWM, ADC, and DAC interfaces, along with embedded Lwip and FreeRTOS. It provides a small 802.11b/g/n Wi-Fi + BT/BLE SoC module and a low-power dual-core 32-bit CPU running up to 240MHz with up to 600 DMIPS. For IoT applications that need camera input, wireless connectivity, and a compact DIP form factor, this module covers those requirements. Note that the OV2640 camera is included, while the OV7670 camera must be purchased separately if needed.
