·       Complete power optimized stack


CEDARBURG, WI (August 15, 2013) – LSR (LSR), the leading developer of RF modules and wireless products announces the addition of the TiWi-uB1, Bluetooth® Smart Module, to the growing TiWi family of products.

Designed for use in a wide range of applications, the new TiWi-uB1 provides low power Bluetooth Smart connectivity at a cost point that is competitive with Asian suppliers.  LSR’s superior integration support and extended product lifetime sets the TiWi-uB1 apart from the competition.  The module includes an integrated Hybrid™ trace antenna for maximum range performance in one small package measuring only 11.6 mm x 17.3 mm.  Because it uses just 12.6 mA in transmit mode and 15.7 mA in receive mode, the LSR TiWi-uB1 is perfect for body worn medical sensors, sports and fitness sensors, remote controls and any other application that requires connectivity to a smartphone, tablet, or other Bluetooth Smart devices.

The TiWi-uB1 provides multiple configuration options: its single-chip configuration allows applications to run on the CC2541 from Texas Instruments (TI), while it can also be configured with a network processor interface for applications running on an external microcontroller.

“The Bluetooth Smart market is growing quickly as device manufacturers look for ways to wirelessly connect sensor-based applications to the millions of iOS and Android smartphones and tablets. The TiWi-uB1 from LSR provides manufacturers with a low-cost module, tools, software, apps and services to help device manufacturers get to market faster,” said Sid Shaw, global marketing and business manager, Wireless Connectivity Solutions, TI.
