Ultra low power Bluetooth modules

Through the close relationship between Roving and CSR, Roving Networks have developed a solution with the lowest power consumption, richest feature set and best RF performance.
The majority of our Bluetooth modules are based on the proven CSR BlueCore 4 platform and use the Bluetooth v2.1 stack with EDR (3Mbit/s) support. EDR support allows for much faster data transfer compared with earlier revisions of the Bluetooth stack, this enables far more usability and opens Bluetooth up to a far greater range of applications including real-time sensors and PC peripherals. The modules are available in various formats with different features depending on what is needed. Interfaces are UART, USB and Bluetooth. Available in smd and through hole packages, with and without on board antennas, designed for short and longer range applications.
