I bought an Ihome speaker years ago that had both the input and an output jack. The output allowed me to do the same as this module does, but they dont sell that type of speaker any longer. You could turn any stereo into a bluetooth system instantly. Thanks for sharing this item.

It's a Bluetooth version of what we used an RF modulator for in olden times.

I use these to add Bluetooth audio to old tube console stereos. They usually have a line in for a tape player you can use for input. Range on mine is about 15 feet.

i use hw 425 module, it has a facility to connect pen drive & a key pin to connect 5 switches for vol, next/prev & pwr.

Hey man i have this module and here are some things I have found..
The battery connection points are directly connected to the 5v or vbus of the type c connector..so don't connect type c and battery at the same time..also the module will only work upto 3.7v as mentioned and when the battery voltage will be approaching 3.7v it will say low battery and keep saying in certain intervals..also you can directly use 5v on the battery solder pins to power the module too..but verify this once after connecting type c and measuring the voltage at the battery pads and i think it will show the usb voltage :)

Add one of those li-ion charger modules with over discharge protection so you can make this a rechargeable Bluetooth audio module

Ordered three of them, look handy. Thanks for that.

This is great. I've just bought a 4k Samsung TV that has no analog audio output. I can connect it to my favorite stereo minisystem using this bluetooth recever module. Thanks.

Thanks for the video. 5 arrived today. Brilliant.

I would like one that can take audio in from a headphone with microphone to work with my mobile phone for two way use. It would be nice if there could be a module for the other end so I could use it with a cordless phone.

ATTENTION!! If a lithium battery is connected to this device, do not use its USB port. The board delivers 5v to the battery and will end up destroying it, it may even cause a fire. It must be powered by USB or with a battery with its own charger, never use both options at the same time.

Thank you for your posting. Are you able to tell me if both channels in phase when playing a mono source and whether the device provides proper stereo when given a stereo source, or just mono from a stereo source? Thank you. Kind regards.

Hi, nice video 👍I would like to do the opposite: add a similar module to my old tv to listen videos from my earbuds. Do you know if it's possible? Any idea would be appreciated

[jaleHD]

Thanks, time to make my own speakers 👌🏾

[endadalton]

Hi, great video. If you connect rechargeable battery will it recharge throw the USB C connection. Thank you

Another 1$ for a 5V step down converter and then install both boards into the boombox

[WillieStubbs]

Wonder if the audio out would make Christmas lights dance?

If you solder a baterry to it, you will need to add a on/off switch else it will work forever..
