DollaTek Bluetooth Receiving Module, Portable Bluetooth Audio Receiver Board AS1711BT DC 5-35V Wireless Electronic Module Bluetooth Chip for Headphone DIY Home Stereo

I had an old ipod dock/speaker with no Bluetooth capability. It was pretty quick and easy to find a DC power line within that and hook this up. The wide voltage compatibility makes this much easier. The dock had an aux in so the audio connection was similarly easy. The only wrinkle in my plan was that the dock was supplying power continuously to the board so it grabbed my phone's Bluetooth connection wherever was nearby. I did not get a chance to listen critically to it since this was a pretty average speaker. And then that speaker died (of unrelated causes). But I like the ease of use, the thoughtful (e.g. different connection options for audio out) and quality build. I plan to use it again with an older NAD amp or possibly on a friend's old, non-Bluetooth car stereo. Low price makes it particularly easy to recommend.

Used one to add Bluetooth to a portable radio. Used another to add second Bluetooth to Nissan Micra so that my wife can listen to podcasts without using the Aux cable connection. Most phones can operate two BT devices so her phone now connects to the car radio BT for handsfree calls and the DollaTek BT for podcasts. So long as Aux selected on the radio the podcasts can be heard. Found power for the board from behind the 12V accessories socket and connected the audio to the connections at the back of the AUX socket. All Hidden and works fine. The audio output level from the DollaTek appears not to be LINE level so there is no chance of over-driving the car radio, you might have to adjust the media volume on your phone to max if you like to 'blow the doors off'!

Nice package. Just big enough to fit in a Tic-Tac box. Nice and compact and robust.Great for adding BT to an old stereo with a jack or audio plug input.Sound wise, I needed to choose varying EQ ( equaliser) options for my phone to get the best out of it for music.Totally fine for listening to podcasts and things on an old stereo that didn't previoulsy have BT.Seems robust enough. And with varying power inputs, a great unit for home enthusiasts. - Otherise just use a USB charge cable, pair your phone and you're good to go.Probably a bit of overkill of you have old headphones with a jack but no jack output on your phone.

Works great IF you use a 0505 isolator on the power input otherwise its noisy...

Imagine old amplifier from 1977 with high quality bluetooth... Golden era of HiFi is back, even more amazing then it was.Connection is quite simple, but need separate power source or B0505S-1W to avoid ground loop.If anyone need help with connecting it please write to me, I can explain and and help.

Used this to breathe ne life into an old amp and speakers. It now can connect to my phone so I can play Amazon Music -or any other service through the speakers. Brilliant! Works of a standard 5v USB supply and the 3.5mm socket connects the audio to the amp. Great value for money!

I bought this because of the voltage range, I have the old makita dab radio, and had to plug in a wireless Bluetooth dongle to the aux socket only issue is if you forget to charge it you can't use it this bluetooth board has been fitted inside the radio and takes power from the radio itself, the sound quality is very good for Bluetooth,,

Great little bluetooth audio module! I used it to give my car stereo bluetooth audio using the 3P connector and the sound quality is great. I especially like the buttonless on/off and connection functionality, I simply wired it into a 12v ignition-switched circuit and now it turns on and off with the stereo system, perfect!My only issues is the fact it also connects as a hands free calling device... this would be fine of there was a mic jack to utilise this feature of the chip but there is not. Luckily most phones (Inc. Mine) allow you to disable using a BT device for calls, so all is good there. 😅
