- The DY-SV5W intelligent voice module is a versatile solution for audio control, combining I/O triggering, UART interface management, and ONE_line single bus control. - Equipped with a built-in 5W Class D amplifier, it directly drives 4-ohm 3-5W speakers, providing powerful sound. It supports MP3 and WAV audio formats and includes a maximum storage capacity of 32Gbit (4MByte) via a TF card, allowing easy music updates through a USB connection. - This module features multiple connectivity options: a 3.5mm audio interface, U disk interface, and a micro USB download interface, all integrated into one compact device. - The DY-SV5W supports voice transmission to manage the UART serial interface, enabling functions such as play, pause, song selection, and volume control for up to 65535 songs, with a baud rate of 9600 bps. It accommodates various sampling frequencies including 8/11.025/12/16/22.05/24/32/44.1/48 kHz for optimal audio quality. - With a 24-bit DAC output, it achieves a dynamic range of 90 dB and a signal-to-noise ratio of 85 dB. It is compatible with FAT16/FAT32 file systems and supports TF cards and U disks up to 32Gbit (4MByte). - The I/O trigger function allows for 8-bit I/O ports to activate 8 music tracks or combinations, enabling a total of 255 song triggers. Applications include: 1. Home automation systems where voice commands can control audio playback. 2. DIY projects that require audio feedback or alerts for various trigger events. 3. Educational tools that use sound to enhance learning experiences or provide interactive feedback.
