Product Introduction

The DY-SV17F is a compact audio output module, with the following features:

24-bit DAC (Digital-to-Analog Converter) output, offering an audio dynamic range of up to 90dB and a maximum signal-to-noise ratio of 85dB.
Supports sample rates (in KHz): 8/11.025/12/16/22.05/24/32/44.1/48.
Built-in 4MB flash memory; you can use a USB cable to read/write audio files to it just like a USB drive.
Supports MP3 and WAV decoded files.
On-board 5W Class D power amplifier chip, which can directly drive 4Ω 3-5W speakers.
Supports up to 7 operation methods, including but not limited to UART, independent IO port control, combined IO port control, and single-bus control; you can switch between them using a DIP switch.
Supports controls like play, pause, track selection, and volume adjustment (up/down).
Can handle a maximum of 65,535 audio tracks, with a baud rate of 9600.

Pin Definition

con1: Mode setting pin 1. After power-on, use it with the other two setting pins to configure the operation mode of the DY-SV17F. A 4.7K resistor must be connected in series.
con2: Mode setting pin 2. After power-on, use it with the other two setting pins to configure the operation mode of the DY-SV17F. A 4.7K resistor must be connected in series.
con3: Mode setting pin 3. After power-on, use it with the other two setting pins to configure the operation mode of the DY-SV17F. A 4.7K resistor must be connected in series. Once mode setting is complete, it automatically switches to a BUSY function pin to output the song playback status.
