ESP32-CAM Camera Module for Developers

Product Description: The ESP32 CAM WiFi Bluetooth Module is an ultra-small 802.11b/g/n Wi-Fi BT/BLE SoC module that boasts a low-power dual-core 32-bit CPU for application processors. With a maximum frequency of 240MHz and up to 600 DMIPS, the module supports a wide range of interfaces, including UART/SPI/I2C/PWM/ADC/DAC. It also features built-in 520 KB SRAM and external 4M PSRAM, allowing for versatile applications.

The ESP32 CAM module supports OV2640 and OV7670 cameras with built-in flash, enabling Wi-Fi image upload capabilities. Additionally, it supports TF card storage and multiple sleep modes, making it suitable for a variety of IoT applications. The module is embedded with Lwip and FreeRTOS, and supports STA/AP/STA AP working modes, as well as Smart Config/AirKiss one-click distribution network and local/remote firmware upgrades (FOTA).

The ESP32 CAM module has three GND pins and two power pins, allowing for either 3.3V or 5V input. GPIO 1 and GPIO 3 are the serial pins used for code uploading, while GPIO 0 plays a crucial role in determining the ESP32's flashing mode. The module also features a microSD card reader, with GPIO 14, 15, 2, 4, 12, and 13 connected to the card reader.

It is important to note that the module requires a minimum input power of 5V 2A, as otherwise, the image may experience instability. Additionally, the GPIO32 pin controls the camera power, and it should be pulled low when the camera is in use. Since IO0 is connected to the camera XCLK, it should be left floating and not connected to high or low levels.

The ESP32 CAM can be widely used in various IoT applications, such as home smart devices, industrial wireless control, wireless monitoring, QR wireless identification, and wireless positioning system signals. It is an ideal solution for IoT applications, as it utilizes the low-power dual-core 32-bit CPU, which can be used as an application processor or a slave to other host MCUs to add networking capabilities to existing devices.

In summary, the ESP32 CAM WiFi Bluetooth Module is a versatile and powerful IoT solution, offering a range of features and capabilities that make it suitable for a wide variety of applications. With its low-power performance, extensive interfaces, and support for various camera and storage options, the ESP32 CAM is an excellent choice for developers and enthusiasts looking to create innovative IoT products.
