ESP Low Power Mode Only Starts When USB Powered I have an Adafruit Feather C6 connected to some sensors. I'm having other issues getting all the readings sent over Zigbee which is kinda pushing me to thinking I'm just trying to do too much with all these sensors in one circuit. Everything hardware/software wise works great on USB. But as soon as I swap over to my 3.7 LiPo, it no longer enters sleep mode. I think this might be brownout / voltage droop issue but not sure. I'm not that experienced with electronics. They are all connected via STEMMA QT in a chain (in the order listed below) If this was the issue, what could I do to attempt to remedy it? Hardware: 1.
