Great product to replace traditional regulator TO92 like 7805 and LM317; I'm happy with this small module.

The sound is clear but is lack of loud, seems to be the sound level is below 75db; the speaker needs a box too big according his size to increase the level sound. For small projects is not a good option. The price is like a 5" speaker one

He probado uno de los 3 que compré y generan un pequeño sonido como si estuviera tocando casettes, es como un gissss. Pensé que era la fuente de poder pero tengo otrs 3 de formato USB y esos no suenan ni blipean al buscar señal disponible. Probaré con pilas de 3.7v, quizás asi si funciones correctamente.
