Serial Wifi Module+Antenna+Pin

ESP8266 Serial Wifi Module+Antenna+Pin Transceiver Arduino STM32 Boost Signal
Product Information 100% Brand New and High Quality. LWIP agreement Support 3 modes:AP,STA,AP+STA Perfect and simple AT commands 3.3V single power supply Ultra-low power for battery powered applications Now your Arduino can get on WIFI without barking the bank Use this module for your next internet of things project,home automation or remote sensor project This module adapts the ESP8266 IC for use over a serial connection using simple AT commands No SPI interface or know-how is required.
NOTE: This module needs a 3.3V voltage supply for VCC and 3.3Vlogic.Not 5V .Connect RX or TX on 5V Arduino will destory this module.You must use a logic level converter or a 3.3V Arduino 3.3V supply on the Arduino Uno has inadequate current capability to power this module.You must provide a separate,higher 3.3V supply(approx.300mA or better)
