Wiznet makers

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

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.

A Paderborn University lab BMS runs a Modbus TCP server on a W5500 hardware socket, port 502, so a ROS 2 node reads cell data and publishes BatteryState.

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.

Higenis HG-ESP32-S3-RLY4-PRO + W5500: an ESP32-S3 industrial controller that drives real relays over UDP via SPI Ethernet.

STM32H5-W6300 (Hygenis Board) Firmware OTA and Web Server Bootloader Project

The source article demonstrates the intended structure of STM32F4 + WIZnet W6100 IPv6/UDP communication, but its code is explicitly presented as an example fram

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.
