- AI-Optimized Performance: The S3 core features specialized vector instructions designed to accelerate neural network inference and signal processing.
- Maximized Memory (N16R8): 16MB Flash and 8MB Octal PSRAM allow for high-speed buffering of 5MP images and large-scale AI models.
- Dual Type-C Design:
- UART Port: For rock-solid programming and serial data monitoring.
- Native Port: Direct S3 connection for USB OTG, UVC camera, or HID emulation.
- Expanded 42-Pin Header: Provides additional access to GPIOs, I2C, SPI, and PWM pins, ensuring you never run out of connections.
- Universal Camera Support: Includes a standard FPC camera header compatible with OV2640 (2MP) and OV5640 (5MP) modules.
- Integrated SD Card Slot: Most Goouuu models include an onboard MicroSD slot for local high-speed data and image logging.

The 42-pin layout breaks out more internal GPIOs of the ESP32-S3, which is critical for complex projects where you need to use the camera, an SD card, and multiple external sensors simultaneously.
In the Arduino IDE, select the board “ESP32S3 Dev Module” and ensure “PSRAM” is set to “OPI PSRAM”. For ESP-IDF, enable it via menuconfig. If set to “QSPI,” the system will not see the full 8MB.
Yes. By using the Native Type-C port, you can utilize the UVC (USB Video Class) protocol to make the ESP32-S3-CAM appear as a standard webcam to any computer.
Yes. The N16R8 memory configuration provides enough PSRAM to handle the large frame buffers required for 5-megapixel image processing.
Yes, the board includes protection circuitry. However, for programming, it is recommended to use the port labeled “UART” to ensure your PC recognizes the serial bridge.
