   "description": "Chip Manufacturer: Espressif Manufacturer Part No: ESP8266EX Datasheet: Click Here RoHS: Yes This is a wifi solution based on IC ESP8266 from Espressif.The ESP8266 wifi module is a self contained SOC with integrated TCP/IP protocal stack that can give any microcontroller access to your WIFI network. ESP8266 module is of low cost and 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.This module has a powerful on-board processing and storage capability that allows it to be integrated with the sensors and other application through its GPIOs,they're so easy to use. You can find an example of code and wiring here: Example Technical Data: Model:ESP-01S 1MB Flash size AP,STA,AP+STA modes available Wireless Standard:802.11 b/g/n Safty Mode: WPA/WPA2 Encryption Type: WEP/TKIP/AES Network Protocal: IPV4,TCP/UDP/HTTP/FTP Frequency Range: 2.4GHz-2.5GHz(2400M-2483.5M) Data Interface: UART/SPI/I2C/I2S/Ir Remote Control/GPIO/PWM Working Voltage: 3.3V Operating Current: ~80mA Operating Temperature:-40~+125 More Information Same Spec Items A-4234 SKU A-2194 Manufacturer Espressif MPN ESP8266EX Can be used with -",
