ESP8266 WIFI Module ESP-12 ModuleThis is WiFi serial transceiver module, based on ESP8266 SoC.The SOC has Integrated TCP/IP protocol stack.It is TTL serial communication interface and its parameters can be set by AT command.It is widely used in networking, smart home project when it is connected to the wifi router.It can be used for remote monitoring of home appliances, bedroom temperature and humidity, and controlling home appliances by the mobile phone.Features:1. Communication interface voltage: 3.3V2. IO Port Package: SMD, all IO ports are led out.3. Antenna Type: Built-in ceramic antenna is available, and you can also use an external antenna.4. Wireless Network Mode: station / softAP / SoftAP + station5. Wireless criteria: 802.11 b / g / n6. WIFI @ 2.4 GHz, support for WPA / WPA2 security mode7. It is very easy to develop projects with AT commandHigh Quality ESP8266 12 Serial WIFI Model ESP-12 ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.WiFi module ESP-02, his core processor ESP8266 is an ultra-low power consumption - WiFi passthrough module, highly competitive in the industry of packaging size and low power consumption technology, designed for mobile devices and Internet application. User's physical devices can be connected to a wi-fi to carry on the Internet or LAN communications to realize networking.ESP8266 with various interface, support UART, IIC, PWM, GPIO, ADC, etc., suitable for a variety of things networking applicationsESP8266 supports three kinds of antenna interface form: board PCB antenna, IPEX interface and stamp hole interface. widely used in smart grid, smart transportation, intelligent furniture, handheld devices, industrial control, etc. PCB antenna and IPEX antenna can be directly used without adding any matching circuit. If design antenna on board, it need esp8266 stamp hole antenna with matching circuit reserved
