An ESP32-S3 DMX box that receives Art-Net over UDP 6454 through a W5500 and drives two DMX512 universes via MAX485, for about $29,33 in parts.

A GPS 1 PPS pulse disciplines an ESP32-S3 clock to ~5 µs; the W5500 SPI Ethernet path is timestamped so LAN clients see 60–100 µs.

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.

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

ESP32-S3 aeroponic controller combining W5500 Ethernet, Wi-Fi, RS485 and ESP-NOW for irrigation, lighting, climate and logging.

STM32 monitors vibration, temperature, and current, detects equipment faults with FFT and thresholds, and reports them via Modbus RTU.

An RP2040/W5500 bridge that forwards Dutch smart-meter P1 serial telegrams to multiple TCP clients with web, logging, NTP and OTA services.

An STM32F103VBTx board combining six isolated stepper axes, 16 sensor inputs, CAN/RS-485, relays, and W5500 Ethernet.

A no_std Rust KNX device stack with W5500-based KNX/IP firmware, TP1/RF support, secure services, and ETS .knxprod generation.

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

Five ESP32-S3 nodes connect ROS 2 to rover motors, BMS telemetry, and status LEDs through W5500 Ethernet and micro-ROS.

Oro Link connects Oro OS CI/CD to physical test systems through an STM32 controller, dual W5500 Ethernet paths, and automated hardware control.

A Rust-based adaptor that exposes a Hamlib rotctld interface for network control of a G-5500 azimuth/elevation rotator.

A Java 21 robotics stack linking Jetson control to ODrive motors through a W5100S Ethernet bridge with binary messaging and watchdog safety.

A PlatformIO-based STM32H743 IMU node publishes micro-ROS data over UDP through a W5500 hardware Ethernet socket path.

A platform-independent Rust driver for WIZnet W6100, using SPI DMA, interrupt-driven service, and lock-free socket data paths.

A+n underwater ROV control workspace combining STM32F407 actuator firmware, a PyQt operator station, YOLO-based barnacle vision, and a W5500 UDP FW path.

Power-Meter-2 measures household energy usage by detecting the blinking pulse of an existing electricity meter and serving calculated power data through a W5500

An STM32F103 gateway uses W5500 Ethernet and MQTT to receive remote motor commands, then routes them to stepper motor drivers through CAN or RS485/Modbus.

Booster NGFW is a Rust firmware rewrite that adds MQTT telemetry, channel protection, USB configuration, and safer control for an 8-channel Sinara RF amplifier.

A self-contained Dreamcast Windows CE image that exposes a desktop shell and experiments with BBA/W5500 Ethernet through a custom mppp.dll link adapter.

A dual-chip STM32H750 and ESP32-S3 combat robot platform that combines mecanum drive, visual auto-aim gimbal control, and W5500-based web status monitoring.
