@B00mb0x has an idea for the high-current devices like the SD-card reader: A separate power supply with an enable pin like the NCV8170AXV300T2G by onsemi.com.
It can be disabled / enabled by an GPIO. Maybe, we could also connect other devices (LoRa?) to this pin to further reduce the overall power requirements?
This ideas is something for a later version, maybe MoleNetv8?
Attention: If implementing, make sure that the EN pin is connected to one of the GPIOs from the RTC domain. These will keep the state even during deep sleep. Other pins might reset and might result into hard predictable errors!
