- A look at a music player with a lot of features from Parts Express. Is it good or just more cheap rubbish? Watch and find out.
Note: I said 4.64mv output when it is 464mv
Look at that automotive dashboard like styling and that screw down flange. This is likely not an unfinished product, but an MP3 retrofit kit for early 2000s cars with a fat useless cassette baffle + controls section and without exposed DIN section, so you can take out interfering parts, make an ugly hole, stick this over, and it'll be fine, and you can reuse existing amplifier which is important when you want to retain trip computer and other such original touches. Apparently someone makes quite a lof of these in Shenzhen area, they're all over Aliexpress too.
I saw this in the flyer email and was wondering about it for a work place music source. I think I will have to pick one up. thanks for the review
Nice for build in garage
the line output is standard such RCA connectors?
Looks pretty decent, perfect match for a home made amp.
It's clearly intended for RV use. 12v, low profile, no security... and requires an outside switch.
There's an app you can download for this. It allows you to turn off the equalizer.
you did a video on a smaller one simaler to this one, and I remember you mentioning a little buzing it had, I never got to finish the video, do you know how to correct that buzzing?
Cool - not too bad at all for 15 bucks. Thanks for sharing.
Very nice John as always straight to the point!
I read all the posts and I did not see my question so I guess I am the only one that has the horrible feedback when there is no sound playing or when waiting to pair up with bluetooth.
Is it on sale on aliexpress or something too? would like link to check out something similiar.
CADR??!! 3:44
CARD !!!!!
CAD stands for CARD and R stands for READER.
Dear sir , my only problem is how to store FM stations ? is there a manual search for FM stations ?
What's the main chip number? You can get a smaller but similar player to these for around $4, would be interesting to see how the very cheap ones compare, they have the same features right down to the 7805 regulator.
ATS2805B
OK totally different then. That chip is at least from a recognised vendor. The one I have is something like 'JTL' and is an all in one, single chip solution. I haven't really tested it, I know it works but I managed to lose the remote and haven't done anything with it in months. I've bought a couple of other, similar very cheap modules and will do some basic tests on them and report back in a few weeks.
It's quite amazing how much tech they're building into what must be $1 ICs these days!
The one I have is this:
www.dx.com/p/cy-153-m-12v-audio-decoder-support-usb-sound-card-fm-aux-volume-adjustable-bluetooth-413960
But these can be bought for under $4 shipped from China.
Cool video mate :)
weird. mine actually fully puts the display and everything on off/sleep. but it doesn't have BT though.
chinese sites and even local electronics markets are full of these things these days, they go from $2 (basic with BT etc etc) and up .....
Im gonna use the CADR slot XD
This would have most likely been built into a powered speaker, and I have seem similar ones to this in speakers.
Mi pregunta es cuál es la marca o la reseña de la plata electrónica
Start at 16:12
Did you try to wire it up to same power supply of amplifier module? Any ground loop problem?
where can we get this
I think you voice command would drive me nuts after awhile. Can you turn it off?
Nope.
It's voice feedback, not command.
Trying to hard wire this to bathroom switch with 12v transformer but my question is I mainly want this as a radio player when switch is flipped when unit powers on does it always start up on Bluetooth first or if u leave it on radio mode will it remember it’s on radio mode or will it go back to Bluetooth I don’t want something that I have to keep pressing source all the time when power comes on
So, to power some speakers, just add an amplifier and use it's outputs into AUX? Does PE sell RCA connector wires?
What do you mean about sound quality ? I search some bluetooth + usb board with panel and good DAC.
How can I raise the signal INPUT to 6v? I want to use this with one of those Chinese amplifiers and I wonder if that Signal INPUT is enough.
I know nearly nothing about electronics. however I am trying to learn what I can. anyway... to the point. would it be possible to use the cheap remote control that comes with it. and add a touch screen. and what ever micro controller . to make a remote that kinda looks like a smart phone. or a small tablet? would that be a worthy project? or more trouble than its worth. or does someone make them already.
I need this kit
How much price this kit
I wondered about these things!
PRETTY COOL HAVE YOU GOT A LINK PLEASE

thanks buddy
If you turn the volume all the way down it says "minimum volume" in a loud voice. That would annoy me mightily.
Hey John Question, could I use this in my truck?
I purchased this unit and would like to improve FM reception. Do you think that a cheap dipole FM antenna would work if I can make it fit the jst connector?
I don't have this unit in front of me but any antenna might work better than the wire included.
are you able to lower the volume off the voice?
Do you think I can replace that regulator for a LM7812 to lower the PSU 24v tension to the 12v that the device supports? Thank you.
It looks like the linear regulator it is using is an ST 78M05. If that is the case, it input voltage is good up to a maximum of 35VDC. The being said, the 12VDC input voltage maximum could very well be due to the regulators package not being about to dissipate the power it would need to for worse case operation with input voltages greater than 12VDCvoltages maximum
Here is a link to the regulator datasheet: www.st.com/content/ccc/resource/technical/document/datasheet/d7/5f/dc/5c/d5/b6/48/7c/CD00000447.pdf/files/CD00000447.pdf/jcr:content/translations/en.CD00000447.pdf
In my previous reply I gave you a possible solution, but to answer your question, no you could not just REPLACE the regulator with a 7812. Doing so would allow up to 12VDC to be applied to circuitry that was most likely designed to handle only 5VDC. Now you could supply the input power to the 78M05 from a 7812, and power it from your 24VDC source, but it would require an external circuit board. Adding a series input power resistor would be so much simpler, providing your 24 VDC input voltage source is rather constant. If you still want a wider input operating range, such as 12 to 24 VDC, then the resistor solution won't work (at least not reliabley).
I'm surprised it didn't speak in chinglish!
william staten Wrong! It says "infrarred" remote control.
how come you don't menting the mic input?
Thanks for the review. Saved me from purchasing... No volume control on the unit is a deal breaker.... :( I always lose my remote or the battery is dead when needed.
LegacyMicro you could connect a volume knob to the system
Thanks for the reply. Yeah, I thought about that after posting the previous comment. I could run it through a class d amp with volume control or something similar. Would you happen to know if the player unit has connections on the pcb for a potentiometer ? That would be convenient...
i have one but i don't know i do know that there is a connection for your audio out (off course) so you could connect one there
Where did you buy it and how much did it cost
the OFF made me LOL.
thanks
Good Video
connecting via aux to a TDA7492P amplifier and i have noise to the speakers..how can i rid of the noise..thank you

hi friend, thank you for your video!
I have 2 module modules
both have
noise
brum
buzz
you understand?
are without signal, and have great interference
you help me ? thanks Vaclav from Czech Republik
Check my video about removing noise from amplifiers which may help.

Hi.. Thank you for your answer..
My problem isn't in amplifier.. I have 3 amplifiers boards for testing audio and all playing good.
But my problem is in decoding board..

But thanks.!!
song fast sistem??
bay Link please
Record audio from line in on sd card?!
No it doesn't have this ability.
Voice feedback for every command sucks!
it would be good if you gave us a link to where you got it, otherwise good review, thanks. thumbs up and a sub from me.
Parts-Express
Where did you get this? On what website
partsexpress.com
can you post a link to the device
No shuffle mode?
If "YAN" on the display means ran or random, then yes.
thats nice. most of these fm transmitters have no shuffle and it makes them very boring after a while
Plays ogg files?!
YEah. I bought that and it is really low volume.
YOU CAN FET ON EBAY CHEAPER JUST TO LET YOU KNOW LOVE YOUR VIDEO I JUST SUBBED TO YOU
The voice in that is annoying AF, too bad most of those have voice and no way to turn it off.
uhmm is not that bad .... :)
It has a very weak output, don't buy it!
How annoying that voice would annoy me
