PROJECT DESCRIPTION

Feature

High-Performance Microcontroller: Built on the XIAO ESP32S3 Plus platform, our board delivers robust processing power and efficient wireless connectivity, making it ideal for complex IoT and embedded applications.
Integrated PoE with Isolation & Power Conversion: Featuring a robust PoE module with built-in isolation, the board safely accepts a 12V Ethernet power input. A high-efficiency TPS563201 buck converter then steps the 12V down to a stable 5V rail, providing optimal power to the XIAO ESP32S3 Plus.
Reliable Ethernet Connectivity: Equipped with an onboard W5500 Ethernet chip and a standard RJ45 jack, the board ensures stable wired network access for seamless data transmission and remote management.
Versatile I/O Options: With dual-sided I/O outputs, you can easily expand functionality and interface with a range of sensors and peripherals to customize your application to exact specifications.
Compact & Ready-to-Deploy Design: Combining integrated PoE, isolation circuitry, and Ethernet connectivity in a small form factor, this board simplifies prototyping and enables efficient deployment in smart home, industrial automation, or network appliance projects.
