ESP8266 ESP-12E WIFI NodeMcu Lua v3 CH340

Description :

• Module integrates 3.3V regulator, GPIO, PWM, IIC, 1-Wire and ADC all in one board.
• LWIP agreement
• Supports 3 modes: AP, STA, AP+STA
• 802.11 b/g/n
• High efficiency AT commands, simple for your development.
• Plug and Play, program your ESP8266 from the for Arduino IDE.
• 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.
• Important note: 
• this is a 3.3V module, ensure it is only connected to the 3V lines on your micro-controller, direct 5V will damage the module. 
• In addition to the 3.3V power supply for the module, 5V TTL data lines also need to be shifted to 3.3V. When using the module with a 5V micro-controller, such as a standard for Arduino,ensure to use a level shifter on the URXD pin - a simple resistor-zener level shifter or voltage divider is sufficient. Again, this is to prevent over-voltage.
• This development board includes the necessary voltage regulation and level-shifting so you can just plug the development board into your computer. 
• No Retail Packages
