Wifi extension module for the Somiqboard. Has internal voltage translator to work with 1.8V and 3.3V processors like DM3730 and AM3517. The extension module is based on the LSR Tiwi-R2 integrated Wifi/BlueTooth embedded module.

Tiwi-R2 product page

The TiWi-R2 Bluetooth and WiFi module is a high performance 2.4 GHz IEEE 802.11 b/g/n Bluetooth 2.1+EDR radio in a cost effective, pre-certified footprint.

The module realizes the necessary PHY/MAC layers to support WLAN applications in conjunction with a host processor over a SDIO interface.

The module also provides a Bluetooth platform through the HCI transport layer. Both WLAN and Bluetooth share the same antenna port.
