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

This project presents a STM32F4 + WIZnet W6100 framework for IPv6 communication using UDP.

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.

This project connects an STM32H750 to a WIZnet W5500 to implement an Ethernet TCP server with automatic IP configuration.

Industrial 3-phase motors often fail unexpectedly due to worn bearings, unbalanced phases, or bent shafts, causing massive factory downtime

This project combines classic RF design with modern digital signal processing to create a compact HF QRP transceiver platform covering the amateur HF bands.
