BT44-191C Embedded Bluetooth Module supporting Point to Point or Point to Multipoint

The ZBA BT44-191C module was designed from the ground up for embedded systems to provide unmatched compatibility, ease of integration, and mimimum total cost of ownership. The BT44-191C-Bluetooth 2.0 Module supports data rates that are three times faster when compared to existing Bluetooth 1.2 Modules while consuming less power. The BT44-191C is a highly integrated Bluetooth 2.0 Module which contains all the necessary elements including the baseband, the radio, the antenna and the fully implemented protocol stack. Therefore, the BT44-191C Bluetooth 2.0 Module represents an ideal solution for developers, with limited knowledge of Bluetooth and RF, who want to integrate Bluetooth wireless technology into their design. The BT44-191C is ideal for enabling cost sensitive designs with a widely supported industry standard wireless protocol. It has been designed to simplify both hardware and software integration of Bluetooth and, consequently, is ideal for adding Bluetooth functionality to embedded designs. The BT44-191C supports SPP in a point (Master) to point (Slave) mode or point (Master) to multipoint (Slaves) mode.
