This project is an ESP32 based OPC UA compatible control board. You may think of it as a demonstration board of an OPC UA server code at: https://github.com/cmbahadir/opcua-esp32 . Any contributions, especially review and suggestions are welcome.
It is sketched in KiCAD. Currently the PCB board is not designed, it may require few additional libraries. Latest schematic pdf is under "schematic_v_0_0.pdf".
