This is an Ethernet development board designed based on ESP32-S3R8. It has excellent Wi-Fi and Bluetooth wireless connection functions, more reliable and efficient wired Ethernet connection, and supports PoE power supply (PoE version only). The development board also reserves a compatible interface to support some for expansion boards. Relying on its rich ecology and open source resources, users can quickly and flexibly carry out secondary development. It can be widely used in Internet of Things, image acquisition, smart home and artificial intelligence projects. Main features: Based on the ESP32-S3R8 high-performance chip, equipped with Xtensa 32-bit LX7 dual-core processor, the main frequency is up to 240MHz Integrated 512KB and 384KB ROM, built-in 8MB PSRAM and 16MB Flash Support 2.4GHz Wi-Fi and Bluetooth 5 (LE), built-in antenna, support external antenna Onboard W5500 Ethernet chip, expand 10 or 100Mbps network connection through SPI interface Support external PoE module to realize Ethernet power supply function (compliant with IEEE 802.3af standard) Onboard USB Type-C interface, support power supply, debugging and firmware download, more convenient development Onboard Micro-SD card slot, support external SD Card storage for images and files Onboard compatible interface, providing a wide range of peripheral expansions and strong compatibility Onboard camera interface, compatible with mainstream cameras such as OV2640 and OV5640, suitable for image and video acquisition Specification:A:with camera Colour:As Shown Material:Plastic Package Contents: 1 x Development Board Only the above package content, other products are not included.
