2: xPico Wi-Fi Shield The Lantronix xPico Wi-Fi Shield (part number XPCW1001000AR-K) is an Arduino compatible expansion module that can help you quickly prototype a design using Wi-Fi with an Arduino computer board. Wi-Fi Kit Contents w xPico Wi-Fi Module w xPico Wi-Fi Shield w 2 dBi Swivel Type Antenna xPico Wi-Fi Shield Description The Lantronix xPico Wi-Fi Shield expansion module provides a simple means to add a feature rich and low power xPico Wi-Fi module to an Arduino computer board. The Lantronix xPico Wi-Fi Shield uses power supplied by the Arduino computer board. The module board includes all necessary regulators to power the 3.3V xPico Wi-Fi module. The Lantronix xPico Wi-Fi Shield has the following features: w One serial port connected to the Arduino computer board w One mini-type B USB device port with an integrated USB-to-serial converter. The USB-to- serial converter can be connected to the xPico Wi-Fi module's second serial port via a board jumper setting. w A second mini-type B USB device port is available for direct connection to the xPico Wi-Fi device port. Note: The USB device port function will be enabled on a future firmware release. w Access to all logic level IO signals on the xPico Wi-Fi device via header pins The Lantronix xPico Wi-Fi Shield is a true IEE 802.11 b/g/n-compliant solution that interoperates with other b and n type devices without impacting network operation. Another benefit of the Lantronix xPico Wi-Fi Shield is that it simplifies code development by not requiring the use of the Arduino Wi-Fi software libraries as the connection manager is built into the device. The figure below shows the xPico Wi-Fi Shield, and highlights all of the various connectors and configuration jumpers. The following table lists each of the connectors and jumper headers along with their function. Further description and pin assignments are included in subsequent sections. xPico® Wi-Fi® Shield User Guide 6
