ESP8266 Serial Port WIFI Module 3.3V SPI for Arduino


ESP8266 Remote Serial Port WIFI Wireless Module 3.3V SPI for Arduino New Version



  • Model:ESP8266-12
  • ISM 2.4GHz
  • PA +25dBm
  • 802.11b/g/n


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