ESP-12E: ESP8266 Serial Port WIFI Wireless Transceiver Module for Arduino

Overview

ESP-12 is a low power consumption of the UART-WiFi module, with very competitive price in the industry and ultra low power consumption technology, designed specifically for mobile devices and IOT applications, user's physical device can be connected to a WiFi wireless network, Internet or intranet communication and networking capabilities.

From 2015/12/28 on, all shippment will be "ESP-12E", It's enhanced version of ESP-12 and 100% compatiable with ESP-12.

Warning

• 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 Arduino will destroy this module.
• You must use a logic level converter, or a 3.3V Arduino
• The 3.3V supply on the Arduino Uno has inadequate current capabilit to power this module.
• You must provide a separate,higher 3.3V supply(about 300mA or better)
