Product Details

Bluetooth v4.0 Audio Receiver Board aptX +EDR 12 VDC

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.

Bluetooth Audio Receiver Board v2.1+EDR 12 VDC is rated 4.1667 out of 5 by 12.
Rated 5 out of 5 by from Easy BluetoothI purchased this Bluetooth receiver for a custom portable speaker install. It works great and is very easy to install. Just add power and hook up RCA outputs. It connects just like any other Bluetooth device. The sound is very clear and I didn't notice any distortion or clarity problems that others have described in the reviews.

Rated 2 out of 5 by from muddie soundReceived this board today and installed it in my boom box, easy to set up, pairs easily, but the sound is very muddy. I am streaming from a kindle fire HDX to the bluetooth board and the sound is not very pleasing. I have the Lepai 2020 amp and the sound direct thru a cable is exceptional but using bluetooth mode the sound is just fair. Even my wife commented on how muddy the sound was. Hopefully in the future parts-express will add a board with the latest generation bluetooth.

Rated 4 out of 5 by from Nice unit after a few upgrades.This is a nice little bluetooth board, but needed a few upgrades to work well.1. Had some ground loop feedback. "Fixed" it with 4000uf @ 16v worth of capacitance on the 12v input. This is temporary until I can design one made to filter the specific noise. Mods aren't pretty, but functional.2. Bluetooth range was terrible. Would barely make it though one stud/sheetrock wall about 10-15feet. Cut the antenna and soldered on 30mm of solid copper from cat3 wire and now it's pretty solid across the house easily up to 30 feet. iphone 4 had better bluetooth reception than ipad mini retina. ipad mini retina had to be horizontal to not cut in and out. Must be antenna orientation. Original antenna trace on board looks like about 45mm, but used 30mm from some guide on instructables.3. Definitely needed some EQ on the amp side. I had it hooked up to a lepai 2020A+ with some some no name speakers in a funky tube I built, or Pyle PCA3 and a set of polk monitors 30BII with KSW12 sub and both need a bump in the bass and treble to sound good. Streaming iTunes radio, my untrained ears think that streaming straight from PC to the PCA3 combo sounds better that ipad over bluetooth. Haven't tried flat EQ or bypass on amps with ipad's internal EQ, but I no reason to since amps EQ sound just fine.

Rated 5 out of 5 by from Case as an enclosure!This Bluetooth wireless receiver works great with my Samsung Galaxy tablet. I just click on sound choose "Sure" and my tablet music player is heard through my sound system. Seems to stay connected even when separated by a household wall too. The board is supplied in a small, black and sturdy card board jewelry box. I mounted the board in the box with some screws and punched holes for the wiring and a fast easy enclosure is created. I placed it behind my receiver. Sound is good, but does not compare to CD quality, but that may be the MP-3 file, or the music player itself. I used the recommended power pack as well. Overall very happy with the purchase.

Rated 4 out of 5 by from I want one for every stereo in the houseI got this to put in my "Bose Beater Boom Box" build. The range isn't 30ft. when installed inside the wood box...maybe the spray bed liner also limits the range a bit. Over all I can have my phone in my pocket and be about 20ft. away before any issue. I also purchased the ground loop isolator because it picks up a buzz when connected to the same power supply as the amp. I like how it connects quickly and will only let one device to be connected at a time...I'm the DJ not you! It would be nice if some shrink wrap was included to protect it for the people that aren't going to mount it inside a box. Over all great little board!

Rated 5 out of 5 by from Simple to use and sounds great!I purchased this product to add bluetooth for an auxiliary input on a tube amp I restored. It was easy to install and connect to. There were no instructions or specifications, but they weren't really needed. There is a DC jack or terminal block for power. You also have two options for the output, RCA or 1/8" mini jack. I will be buying more for future projects.

Bluetooth v4.0 Audio Receiver Board aptX +EDR 12 VDC

Is it possible to rename device name?  I need that people see my brand name while conneting to my sound device.

Asked by: Omers

i'm using this with a lepai 2020 amp is there a way to have both, bluetooth and auxiliary? 

Asked by: beasten15
That amplifier has RCA and 3.5mm auxiliary inputs, but they are both paralleled together. You will have to unplug on or the other in order to have dual inputs for this amplifier.

Is there a full schematic for this board that has other outputs labeled, like an external led? I know there is one on the board, but I would to install a blue on the outside of project case.

Asked by: lanstar
Unfortunately we do not have a schematic available for this board.

Does the audio output need to use the RCA jacks AND the 3.5mm audio jack? Or just one or the other?

Asked by: ddcboy
You can use one or the other, both do not need to be used.

Can you tell me what it's power consumption is @12V. .? And when powered up and no activity for a certain time will it go "asleep" due to inactivity?

Asked by: cmyachtie
Per the manufacturer is it 10ma.  It does not have a sleep mode due to inactivity. It stays on all the time until the power source is removed
