Jesse Hills turns an M5Stack CoreS3 and W5500 PoE base into a touchscreen tester for link, DHCP, IPv6 and ping, after fixing a shared SPI bus in ESPHome.

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 turns a Waveshare ESP32-S3 W5500 relay board into a BACnet/IP node with priority-aware relays, signed OTA, a browser installer and a passed 24 h soak.

ND-PicoDMX-System pairs a Raspberry Pi Pico with a WIZnet W5500 that receives Art-Net and sACN; dual-core firmware and PIO drive four DMX512 outputs at 40 Hz.

Surat factory WiFi is unreliable, so the EaseEmbro MES gives its ESP32-S3 fingerprint terminal a W5500 wired Ethernet option. The platform runs 33 factories.

Ooznest board support in grblHAL/ESP32 routes Telnet, WebSocket, FTP and WebUI over a W5500 SPI Ethernet link on the ESP32-S3, with Wi-Fi compiled alongside.

Native ethernet: config for WIZnet W6100 SPI and W6300 PIO QSPI on RP2040/RP2350, merged by Home Assistant developer bdraco and shipped in ESPHome 2026.4.0.

A WIZnet W5500 on the arm's master RP2040 Pico carries TCP and UDP motion commands from the Arduino UNO Q host, using WIZnet's own ioLibrary socket API.

A peer-reviewed 2026 paper wires an ESP32, three PZEM-004T sensors, and a W5500 Ethernet module into the BMKG Sleman station LAN to log 3-phase kWh in MySQL.

Full hardware TCP/IP stack, eight sockets, a dedicated 32 KB buffer, 80 MHz SPI. UCF Group 21 wrote the comparison down, then measured the chip on its bench.

Five: Modbus TCP, S7, PROFINET DCP, OPC UA and EtherNet/IP. This ESP32-S3 firmware runs the W5500 in promiscuous mode to read Layer 2 frames.

In this open KiCad gateway an ADIN1110 holds the 10BASE-T1L pair and a W5500 carries it onto standard Ethernet, both on one ESP32-S3 over separate SPI buses.

ULSTU put a W5500 on the ESP32 board of its Ackermann teaching robot, so a Jetson AGX Xavier sends JSON-RPC drive commands and reads IMU data over wired UDP.

Going's Senbrino ladder IDE has an MCP server inside, so an AI edits the ladder itself. Senbrino then builds Arduino C++ for a W5500 Modbus TCP board.

Appletini ONE is a Zynq-7020 Apple //e card. Its MCP server reads the live screen over UART, and a WIZnet W5100S carries the virtual Uthernet II.

Web Radio Control's GPL-3.0 azimuth rotator firmware added W6300 support on 2026-08-04. PlatformIO default_envs names W6300-EVB-Pico2 before two Wi-Fi Picos.

hexinttp's ESP-IDF firmware maps Modbus RTU and TCP registers to named points, publishes them over MQTT, and serves 11 MCP tools, with W5500 as default route.

Alexey Titov's Eva node fits a wall box by splitting in two: sensors and a W5500 on the front PCB, RJ45 and a PoE module on the back.

YamBMS is an ESPHome project that merges parallel BMS units into one battery for the inverter. Its two ESP32-S3 Ethernet board files both configure a W5500.

BREMA firmware makes busware's TUL KNX stick answer MCP over HTTP, so an agent can commission KNX devices. A PoE W5500 extension is the wired path.

HeyWillow packages trained WakeNet models for Willow devices, while an external W5500 option connects the voice terminal to local services.

A Bengbu University patent application links RS-485 sensors to a GD32F303CET6 gateway that packages data as MQTT and sends it through W5500 Ethernet.
