Hi every body, some one has done this setup on my stereo already... I have a Panasonic stereo. Here's the problem, I have used tablet as screen in my Land cruiser, since it has every thing I need, customizations, HD screen, portability ( also security from theft as I carry it along with me) camera, Internet, tracking, navigation, In built storage, Bluetooth 5.0 etc. Now when I pair this to my Panasonic stereo consisting bt 3.0, there Is lag in music video songs and audio output, and for some reason the AUX was disabled in my stereo by previous owner. My question is, will replacing aux Jack and also keeping the Bluetooth module, will it work. Or I will have to upgrade the MODULE to bt 5.0..... If available..... Please help.
Repair? Pairing isn't supposed to be without user interfacing how would the board know what to pair to? But it reconnects to the paired device when it receives power again, just tested it.
I really like the fact that even if it is chinese, it doesn't use the annoying lady voice at all, just iphone notification tones, very nice. We need more manufacturers that do this lol
@@MingIslands nope it isnt, they seem to indicate a certain revision. as of writing this comment, the 2023 revision of the xy-bt-mini are now blanked out, meaning there is no notification sound, like at all, they are just silent.
Starting at 5:25 That's the biggest problem with boards today / all surface mount components - any jack or connector that takes repeated stress does not have the mechanical stability and security of the older through - hole components. Eventually those tiny solder points will crack where a through - hole part has itself much more securely anchored.
That could also be remedied with a case that holds things down in place, those thick sticky heat sink 2-way tape pads perhaps on the inside of a sturdy casement???
@@12voltvids Goes without saying. But you have to wonder how long those solder joints will last even though you've redone them. The smaller the mechanical joint, the weaker it is without some form of reinforcement. The old through - hole has that extra reinforcement due to the larger solder pads and the actual strain relief of the leads going through the board. Extra points if it is soldered on both sides and a plated through via. Jason, yes, anything to help keep the part from physically moving will help. But just like in a building, the stronger the foundation, the longer the building will last. Ergo, the stronger the board connection of the high stress part, the longer it will perform well. Any enclosure reinforcement of the part to the board is icing on the cake.
Well this module is going to be built into an old clock radio. I just found another Yorx AM/FM/FM stereo clock radio with the beautiful VFD, just like the one I swapped the VFD tube on, but this one the tube works perfect. It is going to become a bluetooth capable radio. The AM/FM/FM Stereo switch will be rewired for AM/BT/FM stereo.
@@12voltvids not necessarily a commentary on this particular piece, but rather a general statement on the difference between T-H and SMD where repeated stress on connections is concerned. Since your board will be static, that sort of failure should be nil.
I connected a similar bluetooth device to my old Sony music system. However the volume levels is low compared to the built-in cd/radio volume. Any idea how to boost that signal?
He has already done that on an earlier video, Boombox is maybe what he called it, don't remember but an excellent video to help solve that problem. ThriftyAV.
I got the one with the voice, Its connected to my amp & linked to my pc. Working great, no unsoldered tabs on mine - not that i used the micro usb connector. Mines powered from a 7805 regulator connected to the 12v line.
I have a double 12 inch woofer box, I will purchase that BT board, and connect it to a TPA3110 XH-A232 Power board to make my Woofer box a BT setup! Thank you for this video, I willl do the same soldering to mine once I get it in.
*Sir, can we request a video tutorial on installing a bluetooth module on an old DVD player/home theater which doesn't have bluetooth from the factory default (like Home Theater POLYTRON PHT 169).* *Thank you..*
Thanks for the post. Just what I needed. I built a mini amp and I am currently using a coax lead that trails across the lounge floor. This should prevent me and other folk going base-over-apex going across the lounge.
i just ordered mine, used to use another but had really annoying feedback sounds from the bluetooth signal. Was almost like something was wrong with it untill i saw someone else using it. It has the same ic as the one in this video but no other components like the caps on this board, i guess those components are to prevent the feedback from happening
You need to find the input points on car radio mainboard, from the cassette player, and solder an 3,5 mm jack audio wire to this unit. This would be the difficult part. Put the unit back in the dashboard and route the audio wire under the dashboard in order th have the jack connector near the cigarette lighter. Then buy a 12 v lighter socket charger and find the best solution to mount the bluetooth module on it and power it. At this stage you have a functional BT connection. In order to make the car radoo cassette player to play the audio coming from bluetooth, you need to take appart a audio cassette, remove all internals, like band spools, put back together only the casing and insert it into the player. That would start playing, but the audio signal would be from bluetooth. Done. I did this 15 years ago on a Dacia Logan first gen which had only radio cassette player. Instead of using bluetooth, I connected the 3.5 mm jack to my MP3 player, and years after that I listened my MP3 music in my car. I sold it this way, and the buyer was happy to connect his phone to the player.
Well, you sold me, I am going to buy a couple of these, many things you can add this to with such a low power requirement. First hack is a Soundesign 6828AGA, I'll let you know how it goes. If it goes well, I will take it back out and recycle the stereo as I was about to throw it out. Then I'' be adding to a few other things.
Is this board stereo or mono? I bought 2 different (they are not " xy bt mini") modules. All of them had a two outputs (right - left) But when measure the outputs, i saw right and left pins short circuit. They are not stereo. So mono..
Really enjoyed your review! Did you happen to check how it did on just 3.7v? I can think of a couple of ways to use this with a 3.7v LiPo battery? Also nice work on repairing the power and input jack.
@@superatendedordeb0lud0s34 depends if battery has protection circuit, but I wouldn't trust charging from this board, best way would be to use separate charging board like boards with tp4056 from aliexpress, they are rather cheap and reliable, and you should look for ones that provide undervoltage protection as well as charging
@@superatendedordeb0lud0s34 Not sure, those mini adapters can have lesser sound quality and annoying announcement voice, but if aren't concerned with that it should be ok.
Hey good video. Cool. Can you show me how to make a small bluetooth player with a rechargeable battery. Im trying to redo a small transistor radio. Its small and trying to figure it out. Thanks for the good videos
Remember that Bluetooth operates in same frequency band as 2.4g wifi. Wifi has much more power and can easily drown out the very low power Bluetooth signal. Bt was originally developed to connect your phone to a headset or your car. Out on the road there are not dozens of close by routers competing for bandwidth.
i was wondering can i use the jack as an input from for example phone? and if not how can i use 3.5mm jack as input because i'd really like to have it also. Thanks!
I don't believe so, because the mute on the bluetooth receiver controls the power amp, so when it is not actively streaming over BT it keeps the amp in mute mode
Would this be good for adding it to a car radio, my car stereo has a rear auxiliary connection so I was thinking of splicing this into the power wires and connect to the auxiliary to add bluetooth to my radio without using those other bluetooth receivers with all those cables sticking out
I bought two of them from AliExpress it was 1.5$ each The sound quality is decent the range is 6-7m. so I soldered a 45cm. wire to the antenna and I extended double range it's worth for the money. Just I have a problem with the name of the bt devices. They have the same name so when you connect you dont know wich one you're connecting. Do anyone knows how to change the name of the device
@@KuntalGhosh True, it costs little money, but I think it’s part of the CCP plan to take over western civilization. To send a letter to the other side of the world is more expensive than that.
Hey In the description of the product stands it's says ,the Bluetooth device is ready to pair, but you say it just beeps. How can I know if it really just beeps?
Cool little device, thanks for reviewing it. Allows you to have bluetooth in older equipment, just need 5 volts & line input. And it's dirt cheap.
I recognize the tones from a cheap BT speaker I got a year ago so now I know what chipset they used :)
Instablaster.

Does this have that voice prompt, "The bluetooth device is connected ah successfully" (with a very heavy Chinese accent)?
I have one that says: Bat Tree low, prease chahge.

Can you show how to add an external antenna to a MS49SF4 board. I use a Feiyu Tech GW2 Gimbal & Remote to pan and tilt my camera from a distance, but it has such a ridiculously short range. Thanks!
You would have to build a power section to drive a distant type signal for antenna. Not feasible
I've added a different device but still a Bluetooth module to my 1990 car radio and also to my Akai reel to reel player.
That’s a great little Bluetooth board pre-built for just a few dollars!

It is capable of 16bit 44.1khz stereo sound which is similar to cd quality but it is compressed audio due to limitations if bluetooth.
