ESP32Dali is project to interface with DALI compatible lighting devices using ESPHome project. The board supports isolated communication to DALI bus as a master device and the board can also work as 18V DALI power supply from single 5V supply. ESP32Dali is a single 2-layer matchbox sized PCB to host ESP32-WROOM-32 and required interfacing components. The schematics and board files are in the hw folder (KiCanvas, pdf) 3D step files and printed enclosure are also available. The software is based on ESPHome project and its installation is documented in the software README.
