    PAM8403
    just got my order in. bought a couple to play with, wasnt expecting much.. hooked them up to a pair of 18650 in parallel (about 4.1V charged) and to some 3 inch full range in TL. The first impressions were: "oh crap!"... I then opened a bottle of wine and let them play.. about 30min in it was like "excuse me?!, did i miss something??" They opened up like i never saw before, low end was there, good mid and treble. I was starting to wonder if it was the wine.. i then plugged the li-ion charger, voltage went up, sound got better right away.. again (WTF is going on here). Spec sheet does not begin to describe what it sounds like.(please bear in mind I write this is as a $1,99 chinese amp with 1,5-2w of power the size of your thumb witch i thought would be a joke)
    I then went to the source and tried to up the volume. That is when it all went downhill. This amp has a very narrow sweet spot, after that there is a huge cliff of distortion.
    For the price/efficiency/size/flexibility/availability i do not see any other options on the market. With some nice efficient 4ohm speakers possibilities are huge

    perfeito adorei gostei muito bom o produto recomendo a todos.
    adorei perfeito muito bom amplificador, Recomendo a todos para projetos de d i y observação trabalhar com 5 volts no máximo para segurança é bom não passar de 5 volts mas ele trabalha frio e dá um som muito bom responde de 18 a 20000 hertz muito boa qualidade de som estéreo 2 canais na mesma placa não consome nada de bateria é muito econômico dura muito apenas com a bateria do celular boa compra perfeito excelente vendedor muito bom recomendo.

    Обыкновенный pam8403.
    Миниатюрный, питание строго 5 вольт т.к. на плате отсутствует стабилизатор напряжения, мощность, как показала практика желательно в районе 2 ампер, лучше больше.Контактные площадки луженые, но парятся к ним сложно, рекомендую впаять туда гребенку для удобства комутации.

    Very simple design works great definately worth the rating given. Easily solder 2 speakers + Input L & R audio line-in, add 5v power source with ground and away you go. Great for a small audio project such as mine, Im adding bluetooth to my surround sound 5 ch pc speakers system this PAM8403 made mono to stereo a breeze.
