EEPROM memory (U11 / AT24C02D) at Jetson Nano Carrier board

I would like to know the purpose of EEPROM memory (U11 / AT24C02D) at the Jetson Nano Carrier board.
Should we add the same memory to our custom Jetson Nano/Jetson NX carrier board design?
Is it mandatory or optional?

hello pinchasb,

it’s optional, an EEPROM ID for your custom board is not required.
you may also refer to developer guide for more details,
for example, Jetson Module EEPROM Layout and Jetson Nano Platform Adaptation and Bring-Up.
