Mini SD Card MP3 Sound Module For PIC Arduino WTV020-SD

The Mini SD Card MP3 Sound Module is a versatile mass storage voice module capable of accommodating SD cards with a maximum capacity of 1GB. It supports WAV and AD4 audio formats, allowing for efficient audio loading. Powered by the WTV020SD-20SS core chip, it offers various control modes including MP3 control mode, one-to-one key control mode, power-on loop control mode, and two-line serial control mode.

Designed for compatibility with PIC, Arduino, and other platforms, the Mini SD Card MP3 Sound Module utilizes WTV020-16S and WTV020-20S package chips as its main selections. Voice updates are easily performed via an SD card reader connected to a PC. Control commands can be modified by editing TXT files stored on the SD card.

This module supports the FAT file system and enables playback of ADPCM WAV files. It offers flexibility with control modes including two-wire serial, key methods, and UART232 serial communication. Additionally, it supports automatic speech recognition and various speech sample rate formats.
