I am looking at using the WROVER as a data logger and wondering if there are any tutorials out there for using PSRAM and RTC?

If these can be used and data plus time retained during power down (I can add a small lithium cell) then I don't need to add external RTC and Memory modules

Thanks

Sorry, it's not possible to keep the internal RTC powered while the rest of the chip is powered off. Closest you can get is to use deep sleep.

To keep psram powered up you would need to keep the LDO on and also put the flash chip in standby to save power. Can you keep the ldo on in deep sleep?
