We are designing a board that will use the Orin Nano. I have two questions regarding the RTC circuit:
- What is the expected current consumption of the RTC in the Orin Nano?
- The Orin documentation says that a supercapacitor cannot be used because the PMIC_BBAT pin does not provide charging. However, are there any issues with using a supercapacitor if we include an external charging circuit (using a low-leakage diode)?
