Bluegiga WT11u Bluetooth® Class 1 Module

The Ideal Solution for Long Range Connectivity

WT11i is being replaced by the new version WT11u. The WT11u is a fully integrated Bluetooth 2.1 + EDR, class 1 module combining antenna, Bluetooth radio, and an on-board iWRAP Bluetooth stack. The WT11u constitutes the ideal solution for developers that want to quickly integrate long-range and high-performance Bluetooth wireless technology into their design without investing several months in Bluetooth radio and stack development. It provides a 100 dB link budget ensuring long range and robust Bluetooth connectivity and uses Bluegiga's iWRAP Bluetooth stack, which is an embedded Bluetooth stack implementing 13 different Bluetooth profiles and Apple iAP connectivity. By using WT11u combined with iWRAP Bluetooth stack and excellent technical support, designers ensure quick time-to-market and low development costs and risks.
