The BT-1 module is designed to integrate wireless Bluetooth audio from smartphones, tablets, or laptops into speakers and subwoofers, car audio applications, and remote wireless amplifiers. Additionally, this module may be used to create a wireless link between a Bluetooth source and a traditional amplifier, receiver, preamplifier, or mixer.
Features of this Bluetooth v1.2 compliant receiver module include a small 2" x 1-1/2" form factor, a Class 2 range of up to 15 meters (49.2 feet), and 16-bit A2DP support for true stereo output. A USB A-Male plug and a stereo 3.5 jack are pre-attached to the module for quick connection and use. The USB A-Male plug is used as a power connection drawing 5 VDC off of the USB bus from a computer or powered USB hub.
