ESP8266 Prototyping Adapter Board For ESP-07, ESP-08, ESP-12

Description
ESP8266 Full IO ports Adapter Board [For ESP-07, ESP-08, ESP-12]  package contains of a WeMos ESP8266 module adapter plate with IO lead out that are developed for ESP-07 ESP-08 ESP-12. This shield is a peripheral board that can add a full IO serial port or a test board with IO lead out to the WiFi ESP8266 boards without any module. 
The ESP8266 series module is based on an ESP8266 WiFi module and one and more peripheral board. The ESP8266 boards are WIFI Arduino shield boards with a 160MHz, 32bit self processor and TCP/IP protocol, that can add Wi-Fi communication capability to the Arduino and microcontroller boards and also supporting the APSD and VOIP protocol. The ESP8266 module has enough processing capability and storage to be added with other simple boards with at least expansion up-front and minimum loading during runtime. The ESP8266 development board is interfaced with other boards through the I2C, UART, and SPI serial communication protocol. Communication with ESP8266 and its configuration is performed through the "AT Command" instructions. The ESP8266 can incorporate with another simple usual board such as this micro switchboard, the sensor boards, driver boards, and so on, to add WIFI capability to these boards. So all the ESP8266 boards have uniform interfaces includes GPIO, I2C, UART, and SPI serial communication header pins.    

Features
Reserved LDO place on the back of the board
10K resistor between CHPD and VCC, to enable chip
10K resistor between GPIO2 and GND
GPIO15 to GND for normal flash boot mode

Note:
Need to solder 3V regulator by yourself.
Only need power VCC GND for power up the module, and TX, RX for serial communication.
