W5500

Building an LTE-to-Ethernet Gateway with nRF9160 and W5500

An ESP-IDF firmware that turns an ESP32-WROOM32 with a W5500 into a deterministic industrial process simulator served over Modbus TCP on port 502.

A sub-25 mm iSpindel alternative that broadcasts tilt over ESP-NOW to an ESP32 + WIZnet W5500 gateway, which relays readings to MQTT and Home Assistant.

ESP32-S3 Commercial Access-Control Controller with W5500 Ethernet

PACE HMI: Connecting the RAMMP Robotic Wheelchair via RTPS with ESP32-P4 and W5500

This project implements a BLE sensor concentrator on the Nordic nRF52840 DK and adds a wired TCP uplink through a WIZnet W5500 connected over SPI

ZoneTherm combines seven OpenTherm thermostats, configurable valve groups and W5500 Ethernet for local zone control and Home Assistant integration.

An ESP32 thesis project uses W5500 Ethernet, a FreeRTOS queue and MQTT acknowledgements to explore electrical telemetry timing.

Clock 2 combines GNSS timing, an ESP32-S3 and W5500 Ethernet to serve local NTP time, with PoE power, OLED status and browser diagnostics.

JimBoHa adds BACnet objects, priority-aware relay commands and authenticated Ethernet updates to a Waveshare ESP32-S3 controller with W5500.

Jesse Hills turns a CoreS3 and W5500 PoE base into a touchscreen tester for Ethernet link, DHCP, IPv6 and ping, with fixes for a shared SPI bus.

Zephyr's in-tree W5500 driver is MACRAW only. This repo adds an out-of-tree socket-offload driver on the chip's hardware TCP/IP.

Four UDP echo builds on one NUCLEO-H723ZG, measured for an hour each: W5500 hardware offload against MACRAW and the STM32's own MAC.
