ESP32 practical power saving: preserve gpio status, external and ULP wake up – 5

ESP32 has the ability to take advantage of many energy saving modes, but when you set sleep you also lose the status of the pins, but there is a way to preserve it and we will analyze it. Furthermore, the esp32 has powerful features such as the UPL a low-power processor that can wake you up in case of need.

When you create a new IoT project probably you need to connect microcontroller to a battary power source, but if you don’t use a power saving options your battery will run out in no time.
As a lot of IoT microcontroller, WeMos D1 mini have some power saving mode.
The types are modem sleep, light sleep and deep sleep.
