Product versions
The series is available in several variants, which makes it easier to choose a kit for a specific project. The basic version contains only the Ethernet board, while other variants expand it with an OV5640 camera and/or a PoE module.
ESP32-S3-ETH
Basic development board with Ethernet.
ESP32-S3-ETH-CAM-KIT
Ethernet board with OV5640 camera.
ESP32-S3-POE-ETH
Ethernet board with PoE module.
ESP32-S3-POE-ETH-CAM-KIT
Ethernet board with OV5640 camera and PoE module.
Two power supply methods
The board can be powered via the USB Type-C port or optionally via the PoE module. This solution increases flexibility when deploying the device in network projects, industrial applications, and smart home installations.
Optional PoE module
After using an additional PoE module, the board can be powered directly via an Ethernet cable. This allows for simultaneous power supply and data transmission with a single cable, which simplifies device installation in hard-to-reach places.
Camera and image acquisition support
The board features a camera connector compatible with OV2640, OV5640 modules, and other popular cameras. Thanks to this, the platform is suitable for applications such as video monitoring, image recording, visual data analysis, and AI Edge projects.
