There are really only two or three parts/ modules to this project
The LCD is already there, so no change, but the rest is being replaced.
- New processor – STM8L152R8
- Wifi Module – SPWF01SA (though just seen this is not recommended for the new design. As this is a once off, I’m not too worried about that)
- Temperature module? not looked at this yet
- Power regulator – will probably use a DC-DC converter, but as this is not battery operated, I’m not that concerned about efficiency.
