Samarth Enterprises Digital Power 2x3W Class D Amplifier Board

First things first, The actual size is very small, comparable to a 1 Rupee coin, manual soldering will be a little tricky for beginners.I had two lenovo speakers whose circuit was damaged. Got this chip and soldered the speakers to it. Also, used a Nokia charger as source (5V, 500 mA). It worked well initially but came to know that it the IC is heating badly and need to stop. Then I connected 3 cells (4.5V) and voila ! It worked perfectly without any resistor. Now I can use it as portable speakers ! Clarity is amazing but that depends a lot on the power source.A cell will not have noise as it is pure DC, if using an AC to DC adapter make sure you use a high quality noise cancelling circuit (Built in branded mobile chargers) and if the current rating of your power source is too high, make sure you have a resistor in parallel to the source. Refer to the internet to get the correct rating.

The media could not be loaded.  It is best for 3W 4Ω speaker while powering from minimum 1.2A 5V DC power-supply(A 5V 1Amp mobile Charger can be used).Overall built quality and assembly of this PCB is good.If any have this kind of 3W Speakers then go for it and make one like what I have done here.The price should be 80₹ to 100₹ but I brought it for 145₹.. So, contact with seller before buying and u might get dome less.Update: The board is completely damaged after few month of uses. I powered it from 6V transformer with 5V regulator IC, No switching power supply was used.

Only 3v speaker works don't waste your time plugging in to any other there will be too much noise

It looks good. If there is volume control facility it may be very much useful to use as a mobile speaker by adding a mini Bluetooth receiver.

Product is not up to mark.voice level is very low.Can't run 3W speakers.I tried many time but not good responce.

Good enough sound n good quality of sound just u required good quality of speakers to enjoy the quality of sound very easy to install the board it can run with mobile charger and power banks👍

WOW! Working as expected. I have connected it to my old BPL Cassette player speakers laying around for ~20 years.Absolutely satisfying loud and clear sound when connected to mobile. Kept in kitchen and my wife is really pleased, now she can hear her mobile songs nice and clear. Now these speakers can be used as portable USB speakers in picnic and outings, with a power bank, very loud and clear,

The AMP is excellent and good signal/noise ratio too. But it is working hardly one or three times. Not only this amplifier there is higher model of this PAM8610 digital power amplifier booth sold by Absolute Native Electronics in amazon and i have returned with my won courier charges.And i am waiting for my money or any good amp. (so when i am submitting this review the amazon software is not allowing without marking a star so i marked one.any technical questions you can ask me on [email protected].
