An Industrial Motor Controller Built with STM32 and W5500 — RS-485 and Ethernet Behind One Register Map

ZigBee Coordinator

An open KiCad board merges four serial lines into one Ethernet feed on a W55RP20, driving ioLibrary hardware sockets directly with no lwIP in the build.

ESP32-based IMU sensor device for the natKit BCI toolkit. This device collects inertial measurement data and streams it to the natKit backend via MQTT.

Use esp32-s3-poe-eth to connect to Tesla Powerwall AP and proxy requests to ethernet

UC Berkeley's student rocket team, Space Enterprise at Berkeley (SEB), builds an Automatic Electronic Pressure Regulator (E-Reg)

Weidos doesn't use the W5500 as a plain Ethernet PHY/interface. Its official Ethernet.h-based library talks directly to the W5500's hardware TCP socket (TOE).

OpenAmber replaces the Itho Amber heat pump controller with an ESP32 running ESPHome; the ESP32-P4 build uses a WIZnet W5500 for wired Home Assistant control.

ESP32-S3 and W5500 controller that bridges FRC arena WebSocket PLC data to HUB counters, relays, and addressable LEDs.

A full-stack access control platform linking STM32 door hardware to MQTT, with optional W5500 Ethernet, Wi-Fi, RFID, fingerprint, and remote control.

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.

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.

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.

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.

AmeNote ProtoZOA's NetworkMIDI2_Bridge connects USB MIDI 2.0 devices to Network MIDI 2.0 over wired Ethernet using an RP2040 and a WIZnet W5500 expansion board.

PIXPAPER-213-C is a 2.13-inch, four-color electronic paper display that can be driven from the WIZnet W6300-EVB-Pico2 under Zephyr RTOS

CRANTROL is an ESP32-S3 and W5500 Ethernet remote control platform with 10-channel relay control, Flutter mobile app, Firebase sync, and captive portal setup.

BASIX is an open-hardware PIC18 controller integrating W5500 Ethernet, RS-485, isolated I/O, analog inputs, relays, EEPROM, and RTC for automation.
