ESP32 Forum

I have several different dev boards for the esp32-wroom, and am wondering if there is a way to get some
info as to which board it is when running. Foe example some boards
don't have a blue led, some have but it's either gpio-2, or gpio-5
cheers,

Unless the manufacturer burns some code into efuse or uses an external id chip I don't know how you would be able to tell in software which board you are running on.

apart from reading the mac from the efuse, I could'nt find any
support for reading the efuse, any pointers?
