Lantronix xPico Wi-Fi Embedded Wi-Fi Module Application Note - Page 3

Lab Setup The following labs provide examples on how to use the xPico® Wi-Fi® Shield to connect an xPico Wi-Fi embedded device server to an Arduino® micro-computer board. These examples use Arduino Uno, however other Arduino platforms may be utilized. The firmware may change slightly. Prior to running the labs, download and install the open-source Arduino IDE from the Arduino website: http://arduino.cc/en/Main/Software#.UwYZNvldVKY In order to be able to create a virtual com port from a USB port it is also recommended that you install or update FTDI drivers on your personal computer from this website: http://www.ftdichip.com/Drivers/VCP.htm Jumper Settings This example does not require changing or modifying the xPico Wi-Fi Shield jumpers from their default settings. The default jumper settings for the xPico Wi-Fi Shield are described in Table 1 below. For more information about these jumpers, refer to the xPico Wi-Fi Shield User Guide (part number 900-709-R).
