ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.

ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

Now for Arduino can get on WiFI without braking the bank.

Use this module for your next Internet of Things project, home automation, Or remote sensor project.

This module adapts the ESP8226 IC for use over a serial connection using simple AT commands.

No SPI interface or Know-How is required.



This module requires a 3.3 volt supply for VCC, and 3.3V logic. It is not 5V tolant. Connect RX or TX on 5V for Arduino will

destroy this module. You must use a logic level converter, or a 3.3V for Arduino

The 3.3V supply on the for Arduino Uno has inadequate current capabilite to power this module. You must provide a separate,

higher 3.3V supply(about 300mA or better)

The ESP8225 module is very new on the market and support and documentation for it is currently very limited.


Package included:

1 x ESP8266 Serial Esp-01 WIFI Wireless Transceiver Module Send Receive LWIP AP+STA
