ESP32-S3-CAM N16R8 Wi-Fi & Bluetooth Camera Development Board – 16MB Flash, 8MB PSRAM

Product Description

The ESP32-S3-CAM N16R8 is a compact camera development board based on the ESP32-S3, designed for IoT, robotics, smart cameras, image capture, remote monitoring and embedded vision applications.

The board combines a powerful dual-core ESP32-S3 processor, integrated 2.4 GHz Wi-Fi and Bluetooth Low Energy, camera interface, microSD/TF card storage and programmable GPIO in a compact development platform.

The version shown in the supplied photos includes an ESP32-S3-CAM board, separate camera module and USB/serial programming interface board. The programming board uses a CH340-series USB-to-UART interface.

The ESP32-S3-CAM N16R8 configuration provides 16 MB Flash and 8 MB Octal PSRAM, making it suitable for applications that require additional memory for image buffering and embedded vision workloads.
