AI-Thinker ESP8266 ESP-01S Upgraded version serial WIFI wireless module Transceiver Board

The ESP 01S or ESP8266 WiFi Module is a self-contained SOC and an upgraded version of ESP01. ESP8266 serial module has an integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The esp8266 wifi module Arduino is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers (and that’s just out of the box)! The esp 01s connect to wifi module is an extremely cost-effective board with a huge, and ever-growing, community.

Note:

• This module requires a 3.3 volt supply for VCC and 3.3V logic.
• It is not 5V tolerant. 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 the inadequate current capability to power this module.
• You must provide a separate, higher 3.3V supply(about 300mA or better).

Package Include:

• 1x ESP8266 ESP01S WIFI Module
