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.

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.
