The ZBA ZBS44-411-SPF/M is a general purpose CLass 1 Bluetooth serial port adapter with an external whip antenna. This serial Bluetooth adapter can be used in a wide variety of equipment, especially when a direct cable replacement application is desired.

The BTS44-411 SPF/M Class 1 Bluetooth serial adapter¬ is based on the BlueCore4-External chipset from Cambridge Silicon Radio, a leading Bluetooth chipset supplier. It provides a fully compliant Bluetooth system for data and interfaces with a host PC via a standard DB9 connection and supports EDR data rates.
