We only use Advanced Module, MODULE_ID can be floating without pullup on carrier board?
MODULE_ID pin is for power supply option (5V only for Orin nano or 5V ~20V for Orin NX). You can unconnect it if your power supply is fixed.
If MODULE_ID is pulled up to 3.3V,3.3V must be powered on before Orin NX VDD_IN(12V) or before POWER_EN?
How can you enable 3.3V before 12V? You should be able to find the answer in P3768_A04 schematic.
I want to know that VDD_IN powered on 12V first,then MODULE_ID pulled up to 3.3V,last Module POWER_ON Pin pulled up to 5V. Please consider if this is feasible.
Please refer to reference design. We don’t have other suggestion than that. The power on sequence has been listed in the Design Guide.
