Power consumption in deepsleep
-
Hi all,
I want to reduce the power consumption of my M5StickC in deepsleep-mode. When entering the deepsleep viaM5.Apx.DeepSleep(10000000);the power drops to about 2mA with LCD turn off usingM5.Axp.SetLDO2(false);and
M5.Axp.SetLDO3(false);
With a thermal camera I found out, that the chip next to the display-connection gets hot (see pic) so I think this chip uses at least a part of that 2mA.
Does someone know how to put this chip (name: M5A1 1220) in DeepSleep or what the pinout is to connect its VDD to a GPIO?Any other suggestions to reduce the deepsleep current?
Thanks
Lukas
