The UART port is used for code uploading and viewing serial logs via the CP2102 chip. The Native USB port connects directly to the S3 chip, allowing the board to act as a USB peripheral like a keyboard or a high-definition webcam.
In the Arduino IDE, select “ESP32S3 Dev Module”. Set “PSRAM” to “OPI PSRAM”. In your code, you must initialize the camera_config_t specifically for the OV5640 pins and set the frame_size to FRAMESIZE_QSXGA (2592×1944).
Yes, the OV5640 hardware supports auto-focus. You can control the focus motor via I2C commands through the ESP32-S3 software libraries.
Yes, for professional use. The CP2102 is widely regarded as more stable, offering better driver support across various operating systems (Windows/Mac/Linux) and more consistent data transfer rates for large firmware files.
Yes, the board features deep-sleep modes. However, streaming 5MP video consumes significant power, so we recommend a high-capacity Li-ion battery or a permanent 5V supply for video applications.
