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.
