Critical Link, LLC FEATURES • Compatible with MityARM-335x based Development Kits from Critical Link • WiFi Support - IEEE b/g/n • Bluetooth Support - 2.1+EDR - Power Class • Utilizing LSR’s TiWi-R2 Module - Based on TI WL1271 Transceiver CL TiWi-R2 Expansion Kit 23 April 2013 x actual size DESCRIPTION The CL TiWi-R2 Expansion Kit is compatible with Critical Link’s line of MityARM335x based development kits one is required to interface with this expansion kit. All MityARM-335x based System on Modules support the CL TiWi-R2 expansion kit and can be added to a development kit to add WiFi and Bluetooth functionality. Each kit comes complete with a U.FL cable and a 2.4GHz 2dbi external antenna. It seamlessly integrates into the SitaraTM application processor that is used in Critical Links MityARM-335x System on Modules. It is based upon the TiWi-R2 from LS Research utilizing a Texas Instruments WL1271 Transceiver. Copyright 2007-2013, Critical Link LLC Critical Link, LLC CL TiWi-R2 Expansion Kit 23 April 2013 CL TiWi-R2 Interface Description The CL TiWi-R2 interfaces directly with a MityARM-335x Development Kit through the 41-pin Hirose connector on the bottom of the Development Kit, J700. This interface provides the necessary communications and voltage signals used by the CL TiWi-R2 Expansion Kit. Linux Driver and API examples are available to support the WiFi functionality. The b/g/n WiFi interface works directly with the Linux operating system and common wireless LAN utilities such as WPA Supplicant and WPA_CLI are compatible. For further information concerning the configuration and specifications of the TiWi-R2 module that the kit is based upon please visit LS Research: CL TiWi-R2 Electrical Description The CL TiWi-R2 Expansion Kit provides standard WiFi IEEE data rates up to 65Mbps. The communications interface is routed to I2C0 on the MityARM-335x module that is installed in a MityARM-335x Development Kit. The electrical interface between the CL TiWi-R2 Expansion Kit and MityARM-335x based Development Kit is provided via the 41-pin Hirose header described in Table Please reference the MityARM-335x Development Kit documentation for further details on the pin-out of this connector.
