Low Power Sleep with QT PY and Arduino

Post by ctmorrison »

Can someone please point me in the right direction to implement a low power sleep mode for my QT PY ESP32-S2? I have a program I want to power via battery and have it wake up and run every 15 minutes.

Have you looked at using a TPL5110 or TPL5111?

Interesting. I had hoped to handle it via software, but I'm certainly willing to try an economical hardware approach. Thanks for the idea!
