The ESP32-CAM development board featuring the RHYX-M21-45 camera module is a compact, highly integrated IoT solution that supports Wi-Fi and Bluetooth dual-mode communication. Designed for low-power applications, this board is ideal for embedded systems requiring wireless visual data, face detection, or image transmission. It offers robust processing capability, an onboard PCB antenna, and micro-SD card support, all in a space-saving form factor.
Whether you're developing a smart home camera, automated farming solution, or intelligent object recognition system, this module is your go-to choice for powerful wireless image processing and control.
To upload code to the ESP32-CAM using the CAM-MB board, connect the board to your computer via USB. While holding the
IO0 button, plug in the USB cable. Once connected, release the button. Then, select the correct COM port in your software and try uploading again.
Note: The ESP32-CAM module
RHYX-M21-45 does not support JPEG format. If you see the error message:
E(461) camera: JPEG format is not supported on this sensor Update your code as shown below:
// config.pixel_format = PIXFORMAT_JPEG; // for streaming
config.pixel_format = PIXFORMAT_RGB565; // for face detection/recognition
Comment out the JPEG line and use
PIXFORMAT_RGB565 for compatibility.
The ESP32 CAM does not come pre-assembled with the camera. You'll need to connect the camera ribbon cable to the board, a task which can be somewhat challenging. It's essential to ensure proper connection, as the camera will not function otherwise. Forceful insertion can damage both the camera and the connector. We recommend using tweezers for precision and urge you to exercise patience during this process.
To reliably test the ESP32-CAM, you'll need a high-quality Micro-USB cable. Most cheap cables or standard phone charger cables can't handle the higher current demand of the board, especially when the camera is active. While these lower-quality cables might allow data transfer and show output on the serial terminal, they often fail to provide sufficient power for the camera, leading to errors during operation.
ESP32-CAM Setup Instructions:- 1. Do not upload any code initially—the board we’ve provided already comes with default firmware preloaded.
- 2. To test the ESP32-CAM, first connect the camera ribbon cable to the board. (Important)
- 3. Insert an SD Card. (Important)
- 4. Use an MB programmer board and power the setup with a high-quality USB cable. (Important)
- 5. Then, on your phone, scan for available Wi-Fi networks—you should see a new network named ESP32-CAM/ HW297C etc.
- 6. Connect to this Wi-Fi network, then open a browser (preferably Chrome) and go to the IP address: 192.168.4.1. Once the interface loads, scroll to the bottom of the page and click Start Streaming to begin viewing the camera feed.
