Choose this Bluetooth 4.0 receiver module for adding wireless Bluetooth functionality to nearly any device: active speakers, powered subwoofers, vintage stereo receivers, as well as desktop and laptop computers for streaming music from your smartphone or tablet.
Built on a Bluetooth v4.0+ EDR platform, this module features aptX® decoding for a wider frequency response of 16 Hz to 20 kHz, better fault tolerance and lower latency over older Bluetooth versions, and better overall sound quality. Secure simple pairing (SSP) improves the pairing experience between Bluetooth devices, while increasing security, and reduced power consumption in low-power mode. Class 2 reception allows for up to 10 meters (33 ft.) of reception, line of sight, while total harmonic distortion is ≤0.5%.
This receiver board also features high quality X7R ceramic capacitors, lower ESR electrolytic capacitors, and separate power chips for the input and output sections to virtually eliminate RF and digital signal interference.
A 2.1 x 5.5 mm DC power input jack is provided for quick, simple connection to many common 12 VDC power supplies (minimum recommended current capacity is 1A, such as the one in the Related Products section). Audio is output via stereo RCA jacks and a stereo 3.5 mm jack, and this module can act as a headphone amplifier for efficient headphones, in-ear headphones, and earbuds. When paired to a Bluetooth device volume is controlled by the source device, such as a tablet or smartphone. Dimensions: 3" L x 2" W.
Note: This device only receives stereo Bluetooth audio. This device does not transmit a Bluetooth signal. Ground loops can occur when using a grounded power source. Please see the Related Items section for the Axxess 3.5 mm ground loop isolator to solve this issue if it occurs.
