hello
there are a lot of threads in this forum about power consumption of AB-01 device in sleep mode.
it seems there are some issues with board in sleep mode when it powered from battery via Vbat connector - JST 1.25.
These issues related to big current in sleep mode when you power it from battery with more that 4v which is usual for LiPo batteries:
on the other hand - there is variant to power the board via 3.3v pin and with this way it possible to have about 4uA of power consumption during sleep mode.
So I decided to check to use LiFePo batteries which has normal voltage 3.3v and connect it to pin 3.3v on AB-01.
Or, for example, is it possible to use supercapacitor to power the board?
Anyone tried this already? Maybe there are some issues with using such power source with Cubecells?
