Laird Connectivity TiWi-R2 Integrated Transceiver Module

Laird Connectivity TiWi-R2 Integrated Transceiver Module is a high performance 2.4GHz IEEE 802.11 b/g/n Bluetooth 2.1+EDR radio in a cost effective, pre-certified footprint. Laird TiWi-R2 Integrated Transceiver Module has the necessary PHY/MAC layers to support WLAN applications along 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. Laird has expanded the line of TiWi Integrated Transceiver Modules.
