Although it is true that IceNav has its own board, etc... the firmware can be used on existing models.

In this case, support will soon be given to the Elecrow ESP32 3.5" Terminal board.

The idea is to give the maximum possible support to existing boards and not limit people's possible knowledge of electronics, etc.

Step by step I will try, if necessary, to give support to these boards... that is, as long as I can test them myself or someone offers help with it.
