## Description

Features: Can use the computer USB port 5V power supply or using a mobile phone charger USB port 5V power supply battery power can also be used high efficiency:90% can provide 3W (left channel) +3 W (right channel) output power in the 4 load and 5V power supply conditions A class, B class amplifier such efficiency is only about 30% D class amplifier is highly respected today D class amplifier efficiency is extremely high, not because of temperature affect the sound quality but do not add heat sink and take less space noise canceling circuit was built in the amplifier board power on / off without pop noise module has a short-circuit current protection and over-temperature protection Application: LCD TVs, monitors/Laptop/Portable Speakers/ Portable DVD players,/game consoles/ Phone / speakerphone Specifications: Operating voltage: 2.5V-5.5V Speaker With:4-8ohms recommended:4 ohms Speaker Power :2-8W Size:21 x 18 x 3.4mm(L x W x H) Color:As the pics show Net weight:1g Package Included: 5*Super Mini PAM8403 Digital Power Amplifier Board Note:Left and right channel output "negative" can not be connected together, otherwise it will burn IC, and should be connected before the horn (load). Rated working voltage 2.5 ~ 5V, the limit working voltage 5.5V

Review: Very compact and works well - First off, the price was very good for a small 3watt + 3watt amplifier. In fact you get 10 cards which I didn't need. I would have preferred to buy say a couple for a lower price. Anyway it is compact with no large coils or electrolytics. This is quite innovative for a class D amplifier. It is still a good idea to put some ferrite beads on the wires though to reduce RF interference. It is powered by 5v, probably a USB outlet and has a reasonable volume. 3 watts is into 4 ohms 10%THD. Each board is stereo. So good for desktop speakers etc.
Review: Works really well! - Bought six of these for general purpose amps in a school electronics lab. So far have built two (using a DC to DC converter from elsewhere on desertcart to provide 5V whatever the students try to connect to it) and they've worked really well. Gain is just enough to drive the amp into clipping with the input driven from a mobile phone headphone lead. Mounting is a little difficult as the board is so small. My first two are hot glued on for the time being, but am going to use self adhesive foam pads for the remaining four.

### ⭐⭐⭐⭐⭐ Amazingly good amp( for price)
*by S***3 on 24 June 2016*

This amp is brilliant, it has good low end and high end for an amazing low price and size, I am thinking about buying lots of these as the 5v power is convenient as it will run off apple plugs/ power banks any 5v USB port, I can do many projects for low prices with this tiny amp,
