How to Build PoE RS-232 Ethernet Conversion with WIZnet W55RP20 on PP-Ethernet-RS232-PoE? Summary PP-Ethernet-RS232-PoE is a commercial RS-232-to-Ethernet converter module built around WIZnet W55RP20. The module converts data from RS-232 serial devices into TCP/IP network traffic and converts received TCP/IP data back into RS-232 data for the attached device. W55RP20 provides the RP2040-class application MCU, W5500-based wired Ethernet, hardwired TCP/IP stack, socket handling, buffering, and firmware execution path needed for a compact serial device server with optional PoE support.
