ESP8266 ESP-12E WiFi Module

The ESP8266 WiFi module was presented when it was introduced as a “Serial to internet” TTL module. Useful for connecting Arduino signs to the Internet. It quickly became apparent that this ESP12 module and its number of GPIO pins that came out can do much more than just add to an Arduino. The processor is much more powerful than the Atmel processor of the Arduino Uno and the memory is much larger (4 MB of flash memory, part of which can be used as a non-volatile file system). The modules can be used as independent microprocessors in their own right, with WiFi connectivity! Make sure you have a good power supply (3.3 volts) as the maximum power consumption can quickly reach around 300 to 350 mA.
