This 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 Wi-Fi router. It can be used for remote monitoring of home appliances£¬ bedroom temperature and humidity£¬ and controlling home appliances by the mobile phone. Features: - Communication interface voltage: 3.3V - IO Port Package: SMD£¬ all IO ports are led out. - Antenna Type: Built-in ceramic antenna is available£¬ and you can also use an external antenna. - Wireless Network Mode: station / softAP / SoftAP + station - Wireless criteria: 802.11 b / g / n - WIFI @ 2.4 GHz£¬ support for WPA / WPA2 security mode - It is very easy to develop projects with AT command About the Adapter Board: It is used to convert the IO ports of ESP-07 to 2.54mm pitch pin headers£¬ so it is easy for the beginner to test ESP-07 and learn Wi-Fi controlling. Before using it£¬ the user should first follow these steps: 1£¬ Solder the ESP-12 to the adapter board; 2£¬ Solder the 3.3V regulator to the bottom of the adapter board; 3£¬ Solder the 1X8P pin header to the adapter board; Because there is a 3.3v regulator onboard£¬ the range of VCC pin on the adapter board can be 3.3V to 5V. Application: Home automation£¬ sensor networks£¬ industrial wireless control
