This adapter is designed to works with a D1 Mini (ESP8266) but it provides convenient header pins to use it with any other uController.
It is designed by Palazzetti using a Si8621 (Silicon Labs Isolator) to provide electrical isolation between uController and Stove electronic.
This design uses exact same schematic and components.
All files are inside schematic subfolder and has been designed with KiCad (free and open source)
I'm producing small batches of this adapter.

Box project (Fusion 360 & STL) can be found into box folder
Source code can be compiled using VSCode/PlatformIO and flashed onto a D1 Mini
