The WT41U is a fully integrated Bluetooth 2.1 + EDR, class 1 module combining antenna, Bluetooth radio, and an on-board iWRAP Bluetooth stack. The WT41U is a replacement for the WT41. The WT41U provides a superior 110 dB link budget and more than 1000-meter line-of-sight connectivity for Bluetooth applications where extreme radio performance or reliability is required. It also constitutes an ideal solution for developers that want to quickly integrate extremely high-performing Bluetooth wireless technology into their design without investing several months in Bluetooth radio and stack development. The WT41U uses Bluegiga's iWRAP Bluetooth stack, which is an embedded Bluetooth stack implementing 13 different Bluetooth profiles and Apple iAP connectivity. By using WT41U combined with iWRAP Bluetooth stack and Bluegiga's excellent technical support, designers ensure quick time-to-market, and low development costs and risks.
The Bluetooth standard has evolved over the years. The latest standard is Bluetooth 5. For new Bluetooth 5 designs, we recommend the latest Silicon Labs BGM Bluetooth Modules and BGX Bluetooth Modules, based on Silicon Labs EFR32BG SoCs.
