This is an Ethernet development board based on the ESP32-S3R8. It features Wi-Fi and Bluetooth connectivity, a reliable wired Ethernet connection, and PoE power supply support (PoE version only). The board includes a camera interface compatible with OV2640 and OV5640 cameras for image and video capture. It provides expansion interfaces for additional modules. Supported by open-source resources and a broad ecosystem, it enables rapid secondary development. Applications include IoT, imaging, smart home, and AI projects. The board is built around the ESP32-S3R8 chip with a dual-core Xtensa LX7 processor running up to 240 MHz. It includes 512 KB and 384 KB ROM, 8 MB PSRAM, and 16 MB Flash. It supports 2.4 GHz Wi-Fi and Bluetooth 5 (LE), with both onboard and external antenna options. The W5500 Ethernet chip enables 10/100 Mbps network connectivity via SPI. PoE functionality complies with IEEE 802.3af. A USB Type-C interface supports power, debugging, and firmware updates. A micro-SD card slot allows external storage. Expansion interfaces provide flexibility for peripheral integration.
