As a starting point let's consider the ESP32 CAM Kit, a development board that comes with an OV2640 Camera Module Receiver and Wi-Fi+Digital Bluetooth Module Kit.
This product is designed to provide low-power dual-core 32-bit CPU with an application processor that can run up to 240MHz and computing power up to 600 DMIPS, making it suitable for various applications.

Notably the ESP32 CAM Kit comes with 520 KB SRAM and external 8MB PSRAM, allowing for ample memory storage. Additionally, this kit supports UART/SPI/I2C/PWM/ADC/DAC and other interfaces, providing versatility in its functionalities. The OV2640 and OV7670 cameras are also supported providing high-quality image capture. The built-in flash feature further enhances its capabilities.

However there are a few limitations to this product. Some customers have reported issues with the camera that comes with the module, but switching to another camera resolves the issue. Additionally, some users have reported that the development board included does not seem to serve any useful purpose. Despite these minor drawbacks, the ESP32 CAM Kit remains a solid choice for those looking for a development board with a camera module.

All things considered the ESP32 CAM Kit is an excellent choice for developers looking for a low-power dual-core 32-bit CPU development board with an application processor that can handle various interfaces. Its support for high-quality cameras and built-in flash feature make it a good option for those looking to capture high-quality images. Thus, it should definitely be considered as a valuable addition to any development project.
