ESP-12 ESP8266 Serial WiFi Module Kit for Arduino / Raspberry Pi
ESP-12 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: 3.3V. 2. IO Port Package: Both SMD and Inline package are available£¬ and the pin pitch is 2.0mm. 3. Antenna Type: Built-in PCB antenna is available. 4. Wireless Network Mode: station / softAP / SoftAP + station. 5. Wireless criteria: 802.11 b / g / n. 6. WIFI @ 2.4 GHz£¬ support for WPA / WPA2 security mode. 7. It is very easy to develop projects with AT command. About the Adapter Board: Used to convert the IO ports of ESP-12 to 2.54mm pitch pin headers£¬ so it is easy for beginner to test ESP-12. Before use£¬ the user should first follow these steps: Firstly£¬ Solder the ESP-12 to the adapter board; Secondly£¬ Solder the 3.3V regulator to the bottom of the adapter board; Thirdly£¬ 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.
