User Manual Of ESP8266 Wifi Shield(AD010)
Description The shield is designed based on esp8266 by Espressif Systems, pin-compatible with Arduino UNO/Mega2560 DevBorad. Which can be used as two independent part, the upper part is for the Arduino UNO/Mega pin-extension board, the bottom part is for the Esp8266 expansion board. Now the Arduino IDE which is higher than 1.6.4 can be installed Esp8266 board package, so you can control the esp8266 board through the Arduino IDE, not just AT Command.
Technical Specifications 802.
Pinout This serial WiFi module board provides interface as shown in PCB view. And each pin functions are silk-printed in circuit board, as follows: LED definition ESP8266-Based serial WiFi Shield has two LEDs. Red color LED is donated to power supply.
Example: This wifi shield allows you operate a Esp8266 controller board through Arduino IDE, without any wire connection, just plug this shield into Arduino UNO/Mega board ,upload the wifi configuration code to start a wifi host or hotpoint. Then use the TCP/UDP Debugging software to monitor your data transmission.
