ESP8266-12E is an enhanced version ESP8266-12, improve peripheral circuitry increases impedance matching, the signal output is better, whether it is stable or anti-jamming capability, have been greatly improved! For users before selecting the ESP-12, it does not matter even if the product has been made, enhanced version is fully compatible with previous firmware, the pin has added the ESP-12 on the basis of six IO ports, SPI mouth leads, develop more convenient, application more extensive!

1.This module requires a 3.3 volt supply for VCC, and 3.3V logic.
2.It is not 5V tolant,Connect RX or TX on 5V for Arduino will destroy this module.
3.You must use a logic level converter, or a 3.3V for Arduino
4.The 3.3V supply on the for Arduino Uno has inadequate current capabilit to power this
5.You must provide a separate,higher 3.3V supply(about 300mA or better)
