The WTV020 module is based on the WTV020SD-20 device and allows for direct playback of audio files stored on a microSD card. The module has outputs that will either drive an 8ohm speaker connected to the SPK+ and SPK- pins, or drive a single-ended amplifier directly from its DAC output via the AUDIO-L pin.

There are several options for controlling the playback including interfacing push buttons for play/pause, track forward/backward and volume up/down. Alternatively, the module can be controlled via a two-wire serial interface (clock and data) that allows for random track selection and playback control.



  • Supports up to 1GB microSD cards.
  • Supports 4 Bit ADCPM format files.
  • Sampling rate from 6KHz to 36KHz for the AD4 file format.
  • Sampling rate from 6KHz to 16KHz for the WAV file format.
  • 16 Bit DAC / PWM audio outputs,
  • Key (push button) mode, MP3 mode, and two-line serial interface mode.
  • Working voltage: 2.7 to 3.5V DC. 3.3V recommended.
  • Quiescent current: 3uA



  • 1 x WTV020 Based Audio Playback Module
