## Description

DollaTek ESP-12E ESP8266 UART Wireless WiFi Shield for Arduino UNO R3

## Features

- Standard pin interface to achieve full compatibility with Arduino Uno, Mega pitch and so on. (Unless standard size arduino, such as Nano, Mini)
- 3.3V power supply using advanced chip (with the official CC3000 power extension board chip even), so 3.3V Arduino board provided more accurate, so ESP8266 like cc3000 officially works as normal, there is no deviation.
- It leads to a WiFi module/service interface power supply to facilitate developers to extend power and maintenance.
- Onboard ESP8266-12 industrial class stable WiFi module in series, using upgraded PCB antenna, signal better.
