Project description

Summary This project integrates an ESP32-S3, Analog Devices ADE7878, and WIZnet W5500 onto a single PCB to deliver an industrial-grade 3-phase power meter. By combining W5500's hardware TCP/IP offloading with a PoE module, a single Ethernet cable handles both power delivery and data communication simultaneously. An onboard web server serves a browser-based UI with no additional software required. This design consolidates precision metering, network communication, and power supply into one board — making it a compelling reference for developers and engineers looking to simplify power…
