      Hi all,
      I want to reduce the power consumption of my M5StickC in deepsleep-mode. When entering the deepsleep via M5.Apx.DeepSleep(10000000); the power drops to about 2mA with LCD turn off using M5.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
