Overview and Specifications:

This is WiFi serial transceiver module, based on ESP8285 SoC which has integrated TCP/IP protocol stack.
It optimizes the filter circuit and reduces power consumption. It is  compatible with ESP-01.
It is TTL serial communication interface and its parameters can be set by AT command. It is widely used in networking, smart home project when it is connected to the wifi router. It can be used for remote monitoring of home appliances, bedroom temperature and humidity, and controlling home appliances by the mobile phone.
With the help of ESP-01 Adapter module, it can be connected directly with the Arduino board and other 5V MCU development board.
