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.
WeMos D1 mini have 2 UART, one on dedicated pins and a transmit-only UART that can be enabled on GPIO2 (D4), It’s very usefully for debug.
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 ESP8266 has plenty of space for your files.
WeMos D1 mini, a little guide to use this low cost but powerful microcontroller with WIFI integrated.
Specification and IDE configuration to start use It.
