DY-SV8F MP3 Voice Playback Module

Product Overview:

DY-SV8F is an intelligent voice module that integrates IO segmented triggering, UART serial port control, ONE_ Line single bus serial port control, standard MP3 and other 7 working modes, simple Dip switch setting; On board 5W Class D power amplifier, capable of directly driving 4 Ω, 3-5 W speakers; Supports MP3, WAV decoding format, onboard 64Mbit (8M bytes) Flash storage, and can be connected to a computer via USB data cable to update Flash storage audio files.

Product Characteristics:

1. Supports MP3 and WAV decoding formats.

2. Support sampling rate (KHz): 8/11.025/12/16/22.05/24/32/44.1/48.

3. 24 bit DAC output, dynamic range supporting 90dB, signal-to-noise ratio supporting 85dB.

4. On board 64Mbit (8M bytes) Flash storage, without the need for a memory card.

5. Equipped with a 5W Class D power amplifier, it can directly drive 4 Ω, 3-5 W speakers.

6. UART serial port controls voice broadcasting function, which can control functions such as playback, pause, song selection, volume increase or decrease, with a maximum selection of 65535 tracks and a baud rate of 9600bit/s.

7. Supports IO triggered playback function, with 8 IO ports triggering 8 tracks individually or a combination of 8 IO ports triggering 255 tracks.

8. Support for One_ Line single bus serial port control, which can control functions such as playback, pause, music selection, volume increase and decrease.

9. It supports 3 configured IOs to select up to 7 working modes and set the Dip switch, which is easy to operate.
