Hi PaasPaas,

You do not need a board definition but you can immediately fill in the values in the C files in the esp32-smartdisplay library. However, this can be used for tinkering but supporting a log of boards is not possible this way. You can indeed use the solution you proposed in https://github.com/rzeldent/esp32-smartdisplay/issues/126. I added some info there...
