STM32 power saving: wake up from RTC alarm and Serial – 6
As usual our microcontrollers give a wide range of wake up sources, we already see a timed wake-up, and now we introduce the wake-up via RTC alarm and Serial of our STM32.

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.
ESP32 practical power saving: store data, timer and touch wake up – 4
ESP32 has the ability to take advantage of many energy saving modes, but if you use more aggressive sleep you can lost session, we look to how preserve the data and how to wake at a given moment in time and via touch.
ESP32 practical power saving: deep sleep and hibernation – 3
ESP32 has the ability to take advantage of many energy saving modes, here we will understand how to put the device in deep sleep and hibernation mode but above all we will try to understand the differences.
