1 PCS ESP8266 ESP-12E UART WIFI Wireless Shield Development Board For Arduino UNO R3 Circuits Boards Modules

Description

Note:Make sure you know how to use it. Scope of application: 1.Remote control aircraft electrical/model/four axis, etc 2.For the smart devices provide networking services 3.Household temperature/humidity/PM2.5 monitor, etc 4.Intelligent switch etc. Features: 1.Onboard four LED displays the status of ESP8266,namely PWR, DFU,  STA 2.Use stackable design,it can continue to accumulate above the other modules, easy to use. 3.Onboard ESP8266-12 stable industrial grade WiFi module with a metal shield, immunity to interference. 4.Built-in 5V to 3.3V TTL level converter to prevent high-pressure for arduino TTL level of the WiFi module damage. 5.Onboard ESP8266-12 stable industrial grade serial WiFi module,using an enhanced PCB antenna, signal better. 6.It leads to a WiFi module power supply /service interface to facilitate developers to extend the power supply and maintenance. 7.Onboard ESP8266-12 standard pitch leads to a stable industrial grade WiFi module all interfaces, enabling developers to easily develop deep. 8.Standard pin interface to achieve full compatibility with the pitch for arduino Uno, Mega and so on.(Unless the standard size for arduino, such as for Nano, Mini) 9.You can quickly switch DIP switch ESP8266-12 industrial grade WiFi stable operation mode(such as operating mode and upgrade mode) module, integrated serial chip, quickly flashing the firmware. 10.3.3V power supply using advanced chip (with the official expansion board power chip CC3000 same),so 3.3V for arduino board provided more accurate,so ESP8266 as official cc3000 chip work as normal, there is no gap.
