TPA3110 Bluetooth Amp Board Review

Advice, try not to solder on camera. TDA? Annotate any mistakes in video editing. Not sure why you've not seen a wattage rating expressed that way before...if you say RMS Watts you've failed...epic fail even. Good luck. Edit: Bass roll off is from input capacitors, high frequency roll off is from the output filters.

Great informative video that answers all my questions. Thank you and keep up the good work.

Bluetooth paired beep is best but power on tone is disgusted, it also should be beep

Great 👍🏾 video. So many videos like this and folks just are saying anything during the video. You're walking through almost everything, which is fantastic.

Question: what if I wanted to connect this to a battery pack? How many batteries would you suggest?

It sounds great

Sir please create new video bcz I have 15 watt 8 ohm speakers so tell me about how to create bluetooth speaker like mine

The function of those 'SW' pads etc depends on which bluethooth module you have installed. Mine has weirdly a FM tuner built-in that gets activated with the switch and some button combo....

Also I had to put a cap over the +/- pins of the bluetooth module itself, or any volume position above 50% would lead to a reset of the device. The internal voltage regulator circuit on the PCB seems a bit weak, when the speaker kicks-in the voltage drops momentarily enough to make bluetooth reset. Tried bigger PSU, Cap on the amp board, but then only a cap over the power rail of the Bluetooth module solved it.

But in general a neat board. Wish there was mode docu, like how to reflash the firmware with custom device name etc.

great job thanks
this device turns off when voulme is up, it disconnects bluetooth conection, is there any answer about this?

Grat video. I have one of these boards. Do you know if there is a way to connect external Aux input to this board? Wondering if its the L-R-Gnd pins under the bluetooth module connector.

В реальности 15ват не возможно получить

Great Video, thank for this.

Can i use 20w speaker??

Can i use 50 watts speaker ?

Thanks for the video. I bought a similar unit after seeing this video. I have tested it on various drivers and it really shines on my hifi speakers. Just a question: what effect does input voltage have on performance and efficiency?

good evening, what charger works with 12 volts and how many amperes for this module?

i ran mine initially through a 12vdc 500mAh regulated wall wart. Sounds okie. Then i switched up to a 18vdc 1A wall wart. The soundstage opened up and the midbass is no longer lumpy. Finally i hooked it up to a Studer 900 24v Linear Power Supply and my jaws just dropped on the floor.

the key pins are so you can add buttons and resistors to enable /on,off/play,pause/next,previous,i think pause is 51k to ground, next is 33k to v+,-previos is 9.1 k to v= and 0R to ground ,,i will make all the proper calculations this weekend and get back to you with the circuit diagram all corect values,will do mute button as well and also a aux line out ,which comes in handy cheers KT

Please wait for me to double check and test values for this weekend thanks

boa noite, ótimo vídeo ,excelente música...

Hi, evening, I got the 30w version of this and I was just wondering what does the KEY do? And any chance on the SW to do it's purpose, like switch off and on?😅

You're making the #1 mistake the way you solder you don't put solder to the iron.

Thanks for the video! By just the appearance, I seem to have the exact same amp. I was wondering where to connect the speakers and my battery and you showed me where in your video 😄

What was the project you were thinking of using it for? A toy?

Does anyone know anything about which bluetooth board this is? I can't seem to figure that out, and I really wanna customise the bluetooth name. If anyone can help me out with that, I'd really appreciate it!

Ty very much finally in English ur video is great and i can understand everything you saying

"Hello sir, I want to run two 15W+15W speakers on this amplifier. So with a 16-volt power supply, how many amps of current can I provide so that the amplifier is not damaged? What is the maximum amount of current I can safely supply?"
