The ESP32 is capable to activate the energy saving modes of light sleep and deep sleep, but in many cases we cannot use such a solution, but it is still possible to apply some options to the functional units for reducing energy consumption.
Let’s set the sleep mode, disable the WiFi and scale the frequency to the CPU.
ESP32 have 2 multiple UART, they are very usefully for debug, and this device have also a core logging system that you can use to debug and control your code.
Serial Peripheral Interface Flash File System, or SPIFFS for short. It’s a light-weight file system for microcontrollers with an SPI flash chip. The on-board flash chip of the ESP32 has plenty of space for your files.
ESP32, a little guide on how to use this low cost but powerful microcontroller with WIFI integrated.
Pinout, specification and IDE configuration to start use your esp32.
