Do you know some similar module with built-in playback and volume controls? (like the ones you would find in a bt headset)
Excellent Video! Thank you!
how's the output sound quality using this module compare when using aux cable?
Thanks a lot for this video
Plz check for ground loop as well?
Of all the Bluetoth modules I have seen working, the MH-M28 is the one that works best. It is well designed. I have several modules of these and they all work well.
which one is best mh18 or mh 28 ?
@@prakashsailayam2030 , they are electronically similar but there is a big difference between MH-M28 and MH-M38.
While the MH-M28 produces only a LINE OUT signal at its outputs, the MH-M30 produces SPEAKER LEVEL at its outputs. In short, the MH-M28 does not amplify any signal and simply decodes BT, transforming it into something that you can connect to an external amplifier (or amplified speaker).
The MH-M38 decodes the BT signal but it already has its amplifier, so you cannot connect its outputs to anything except Speakers.
I'm sorry...i misread your question...So....
In practical terms, it is preferable to order the MH-M28, as it is already equipped with the outputs you need for your service, and the core of the MHM-18 is exactly the same as the MH-M28.
The MH-M18 is just a little more difficult to put into operation.
But don't worry@@prakashsailayam2030 !
Whichever BT module you choose from the MH-M line, you will be satisfied with its performance, without the slightest doubt.
@@revoxjazz8317 Thanks for the Reply and information
If I connect a USB Pen Drive to the USB Port will it play the files on the USB stick ?
Add battey only on?
What is your opinion about the audio prompt when pairing/connecting? Is it annoying or not? i can't really hear it properly cuz the vid is sped up
The audio prompt of these modules is discreet, not too loud and is perfectly acceptable because it consists only of a tone signal lasting one second. Without a Chinese voice, because if that were the case, I would never have bought 8 modules of these for me.
Plz suggest a good bluetooth module, I need to convert my 6 yrs old sony headphones to wireless. Should I use MH-M28 OR M38 or any other module. Plz reply
this one OR VHM-314 OR XH-A252 produce better quality sound?
Hey, Can we directly connect small speakers to the board or we'll need amplifier board too?
You can purchase the M38 version. That has amplifiers for your speakers
good device thanks ♥️👍
Will it work on 12V?
Amigo ese módulo funciona con 3 voltios. Gracias
I have a problem with this module. I want to build a Bluetooth Speaker. When i connect the module to a powerbank, it turns off after a couple of seconds. Is there a sollution?
Some gadgets which can't consume 5 volt throughly and 3.7 volt is better enough, power bank is not for those gadgets. In this case Power bank cannot supply its volt to the gadget and at a time it shuts down to its own way.
thanks a lot!
hello I would like to know if by connecting a 3.7 volt 500mhA lithium battery and then connecting the micro usb to a power supply..... is the connected battery recharged??? Thank you
Also want to know this!
No.
Both are different power sources. Either micro USB ( preferably 2A ) or 3.7 volt lipo / lithium battery.
Headers are given as such.
Never use both.
For lithiumb/ lipo battery, charging has to be done separately.
Hope this answers....
is it works with windows 10?
Microphone input??
is microphone availble?
No.
Did you check? does it really support bluetooth 5.0? they are advertised as 4.2
in manual it support
can i hook this up to some headphones?
Just use a 1/4" (6mm) Stereo to 3.5mm stereo adaptor, and shove it (to the hilt) into that big hole on the side of the unit.
Plug your headphones directly into that without the LEPY and control the volume from your blue tooth mobile phone as they are doing.
The USB is ONLY there, for the 5v DC operating voltage supplied by the mains power plug-pack.
You get Blue-tooth "pairing" direct with the blue tooth the cellphone is outputting.
Hence why you see the cellphone "music-play screen"

Could you put some lithium batteries?
Just a standard 3.7-volt lithium battery is enough. The maximum consumption of each Bluetooth MH-M28 module is 20 Milliamps. With a battery from an old smartphone, a full charge gave 122 hours of uninterrupted operation
But beware, because the module itself does not contain battery charge control electronics, so don’t even think about connecting the 3.7 volt battery and the 5 volt power at the same time. One thing or the other. Never both at the same time.
I bought M38 version to make Bluetooth headphones and it works but ı heard disturbing noise sounds like buzzing. How can ı fix ?
For your information, the headphone output of the MH-M28 module works perfectly and has a very good quality. The MH-M38 module is not intended to connect headphones, but speakers. This module is equipped with two integrated power circuits of the type 8871, which deliver between 1.5 and 3 watts depending on the impedance per channel.
Therefore, if you want to amplify only headphones, investment in the MH-M38 module is absolutely unnecessary. Just use the MH-M28. In addition, as the MH-M38 module has two discrete integrated circuits, the mass of each of them cannot be brought together in a single cable (typical situation in a headphone connection, in which there is a speaker for the left channel, a speaker for the right channel and the referred mass common to the two channels). The MH-M38 module does not support the joining of both masses at a single point. You risk damaging both 8871 power integrated circuits. I am explaining this because I bought the MH-M28 and MH-M38 modules and I know how they work.
@@revoxjazz8317 great explanation ! The best part (for me) of the MH-38 is the USB audio. So you can connect bt and usb but I like to use my own (more powerful) amplifier. Could that be done? By passing the 8871 is''s somehow? I have several TPA3110 XH-A232 boards I like to use for amplification.
Hans de Groot:
Yes, it is possible to do that. I can help you. However, there are some details that you must keep in mind before this type of adventure begins. I don't care at all to help you achieve that because I support your idea 100%. But it has to be by email. Send your contact to revoxjazz@gmail.com and we will understand each other from there, ok?
I believe that you are thinking the right way and ... for the price of the MH-M38, you certainly would not get a DAC that works better than this to connect to a Smartphone ... I almost always do that kind of thing to certain boards which allegedly only serve what the manufacturer says, eh, eh, eh, eh .....!

@@revoxjazz8317 thank you
is it true stereo??? left and right speaker deliver sound separately or not???? test with stereo check youtube videos and reply me please
Yes. it's stereo. I have tested on mine.
@@vismakan6941 thanks
@@vismakan6941 Hey, do you know if I can connect some lithium batteries instead of power cables or that can't be done?
@@juanjoo9832 Hi yes you can. Board has two different possible inputs - 3,7v and 5v. Next to the usb input connector (on the right side) is 3 pads named ”vbat”, ”gnd” and ”5v”. Connect battery to ”vbat” and ”gnd”.
*on the left side.
how is the bass?
Andrei, I just connected a Bluetooth module MH-M28 that arrived yesterday and the critical hearing is this: It works very well, it is recognized in all Bluetooth systems and it is very stable. The only thing I notice is some lack of "weight" in the audio, although it is crystal clear. Here is my contribution.
Stay Safe!

I'm here I just wanted to know what kind of sound it makes when it's turning on and connected/disconnected.
Thank god it's not that annoying lady robot voice
aux?
You can use the included 3.5 mm jack for send audio stereo into any AUX input. No problem at all, with nice audio level.
Does anyone know how to rename them ?
Once you pair it you can rename it on your phone.
@@orbitalweapon7538 I mean like HARD rename..... anyone who tries to connect will still see "MH-M28"
@@snsayy I don't think you can just modify the name you have to completely overwrite the Bluetooth chip
Let's see how it twerks.
Can we disable the "Bluetooth device is ready to pair" start up sound?
I have the same circuit but mine does that on startup 🥲
I'd like to know, too. I have two of these modules, one has the same sound as the author of the video, but the other one has recorded horrible sound, just as you describe.
