Wifi expansion module for the Somiqboard

SomIQ-WLAN is an expansion module for the Somiqboard. It is based on LSR Tiwi-R2 Bluetooth and WiFi module.

Product details


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.
