DFPlayer Pro MP3 Player Module
The DFPlayer Pro MP3 player module offers high-quality dual channel audio with 128MB storage, 24-bit DAC output, and a UART interface. It supports multiple control modes, including Arduino, AT command, on-board buttons, and ADKEY. With USB connectivity, It allows easy music copying and supports various audio formats, including MP3, WAV, WMA, FLAC (Free Lossless Audio Codec), and APE (Monkey’s Audio) for high-fidelity lossless audio experiences. Compatible with Arduino and Raspberry Pi, the DFPlayer Pro is ideal for self-service devices, ATM voice prompt systems, medical diagnostic equipment, in-car high-fidelity voice navigation, public address systems, and voice alarm systems.
