ESP32 CAM Development Board with OV2640 Camera | Wi-Fi & Bluetooth Module

The ESP32-CAM-MB is an improved version of the ESP32-CAM with a USB-to-serial CH340G adapter, making programming much easier since it does not require an external FTDI module. The ESP32-CAM is a small, low-cost development board that integrates an ESP32-S microcontroller with a camera module, making it ideal for image processing, video streaming, and IoT applications. Here are its key features and specifications:

The smallest 802.11b/g/n Wi-Fi BT SoC module.
Low power 32-bit CPU, can also serve the application processor.
Up to 160MHz clock speed, summary computing power up to 600 DMIPS.
Built-in 520 KB SRAM, external 4MPSRAM.
Supports UART/SPI/I2C/PWM/ADC/DAC.
Support OV2640 and OV7670 cameras, built-in flash lamp.
Support image WiFI upload.
Supports TF card.
Supports multiple sleep modes.
Embedded FreeRTOS.
Supports STA/AP/STA+AP operation mode.

Programming the ESP32 CAM Board:

Note: You need to connect IO0 and GND by soldering (jumper wires or a separate switch) before connecting the module to the computer for the code to upload successfully.

1. Required Components

ESP32-CAM-MB module (with CH340G USB-to-serial)
USB-C or Micro-USB cable (depending on your board version)
Arduino IDE (or ESP-IDF)

2. Install CH340G USB Driver (If Needed)

Download and install the CH340G driver for Windows/Mac/Linux if the board is not detected.
- Download CH340 Driver
Check the COM port in Device Manager (Windows) or ls /dev/ttyUSB* (Linux/Mac).

3. Install ESP32 Board Support in Arduino IDE

Open Arduino IDE.
Go to File → Preferences.
In "Additional Board Manager URLs", add:
https://dl.espressif.com/dl/package_esp32_index.json
Click OK, then go to Tools → Board → Boards Manager.
Search for ESP32 by Espressif Systems and install it.

4. Select the Board & Port

Go to Tools → Board → Select "AI-Thinker ESP32-CAM".
Set Upload Speed to 115200.
Select the correct COM Port (e.g., COM3/COM4 on Windows or /dev/ttyUSB0 on Linux).

5. Upload Example Code

Open File → Examples → ESP32 → Camera → CameraWebServer.
Modify the camera model in camera_pins.h:
#define CAMERA_MODEL_AI_THINKER // Uncomment this for ESP32-CAM-MB
Click Upload.
