ESP-12E ESP8266 UART WIFI Shield Development Board For Arduino UNO R3

USB to TTL converter is not required. Compatible with UNO r3 configuration, call syntax. 10 support pwm / interrupt / serial port / i2c scalable gpio. You can update the expansion board or custom firmware with uno r3. Colour: blueUSB to TTL converter is not required.
Compatible with UNO r3 configuration, call syntax.
10 support pwm / interrupt / serial port / i2c scalable gpio.
You can update the expansion board or custom firmware with uno r3.
Colour: blue 
size: 70*40mm
Material: metal 
Onboard four LED displays the status of ESP8266,namely PWR, DFU, STA,AP 
Use stackable design,it can continue to accumulate the other modules on it, easy to use. 
Onboard ESP8266-12 stable industrial gradeWiFi module with a metal shield, immunity to interference. 
using an enhanced PCB antenna, signal better. 
Built-in 5V to 3.3V TTL level converter to prevents high voltage Arduino TTL levels from causing damage to the WiFi module 
All interfaces of the onboard are standard-spaced for easy development by the developer. 
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) 
Using DIP switch can be used to quickly switch ESP8266-12 modle industrial-grade stable WiFi module operating mode (such as operating mode and upgrade mode) module, integrated serial chip, quickly brush the firmware. 
Using advanced 3.3V power supply chip (with the official expansion board power chip CC3000 same),so the provided 3.3V voltage by arduino board is more accurate,So the ESP8266 work as normal like official cc3000 chip, there is no space. 
Scope of application: 
Remote control aircraft electrical/model/four axis, etc 
For the smart devices provide networking services 
Household temperature/humidity/PM2.5 monitor, etc 
Intelligent switch etc. 
Package Included: 1 x Development Board
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
