Microcontrollers are the backbone of countless battery-powered devices, and maximizing their energy efficiency is crucial for long-term operation. In this tutorial, we use a thermal camera to visualize how microcontrollers behave thermally as they transition between deep sleep and active modes. By comparing the PTSolns Nano Flip (ATmega328P) and the PTSolns ESP32 microWatt, we reveal why the ESP32 microWatt is a well-suited choice for low-power applications.
