Még nem próbáltam ki az MP3 lejátszót, de jól néz ki. Köszönöm, Banjó.
Prodotto molto valido. Provato con Arduino UNO e uno speaker da 3W 4Ohm, suona molto bene, anche se al massimo. volume le frequenze più alte vengono suonate con qualità inferiore. Facile da programmare grazie alla libreria fornita dal produttore provvista di numerosi comandi. È possibile collegare anche un tastierino, seguendo lo schema reperibile in Internet, per renderlo del tutto autonomo. Funziona con MicroSD Card
Товар пришёл вовремя,упакован в пакетике.Качество очень хорошее.На картинке кажется больше чем на самом деле.
Good Quality & Working Modules. I ordered 10 Pieces & got a promotional Offer. Very much happy with these. Attached here the pic of my project in which i am using
not yet tested. the circuit is very small and the quality is good. satisfied non ancora provato. il circuito è molto piccolo ed è realizzato con cura. soddisfatto
DFPlayer is a perfect match for wearables or other projects with limited space constrains, specially if used in tandem with Arduino Mini Pros or similar products. Please note that code has to adapt to the relatively slow processing of the module... The only thing worth changing is having the module available with no connectors like the Mini Pro itself (the current solution is breadboard friendly, but does not help in limited space situations)....
I ordered 2 of these modules and both arrived faulty. In both cases, the problem was with the amplifier (the smaller chip on the backside). Without the amplifier, only the headphone output works, while the speaker out remains silent. I could fix one by resoldering, but have to ask customer support about a replacement for the other. After fixing, the unit I could salvage worked very well.
Nice and cheap MP3 player. Please read the technical information at https://www.dfrobot.com/wiki/index.php/DFPlayer_Mini_SKU:DFR0299 It can be used with and without Arduino to control playing MP3 files.. MP3 files need to stored in the root directory.
