MP3 Micro SD Card Sound WTV020 Module Arduino Compatible

MP3 Micro SD Card Sound WTV020 Module Arduino Compatible


This product allows for direct playback of MP3 Audio files encoded in AD4 file format stored on a MicroSD/TF card. The module features an output that can drive an 8ohm speaker using the SPK+ and SPK+ pins. Alternatively, you can drive a single ended amplifier directly from the DAC output via the AUDIO-L pin. This unit also has some few dedicated pins to allow microcontroller signals to control playback features such as play and pause, track forward/backwards and volume up/down. You could also use a two wire serial interface to select the track and send playback controls.

Please note: To use this product with a 5v Arduino such as the UNO, please use a level shifter as the signal lines are not 5v compliant.
