Introduction

This is LinkSprite Anaconda WiFi Shield for Arduino (everything you see on the picture is included except the Arduino board).

This WiFi Shield has built-in TCP/IP stack and all the WiFi related code. Arduino just needs to configure the WiFi parameters using AT command through the UART, or, user can simply treat the WiFi as a transparent serial port after some offline configuration.

Usage

Hardware Installation

To do the offline configuration, jumping TX to MTX, RX to MRX, removing ATMGEA328, and configure the module through the Arduino USB port using the configuring GUI utility [1]. During power cycle, the parameters are saved.
