Frequently Asked Questions
Q: What audio formats does the DY-SV5W Voice Playback Module support?
A: The DY-SV5W supports both MP3 and WAV audio formats with sampling rates ranging from 8 kHz up to 48 kHz, making it compatible with most standard audio files you would store on an SD/TF card.
Q: How do I control the DY-SV5W module in my project?
A: The module offers three flexible control methods: UART serial communication (9600 bps, up to 65,535 tracks), IO trigger inputs (8 ports for individual or combined triggering of up to 255 tracks), and a One-Line single-bus serial interface. You can also select from up to 7 working modes using the onboard DIP switch and 3 configuration IO pins.
Q: Do I need an external speaker amplifier with this module?
A: No! The DY-SV5W has a built-in 5W Class D power amplifier that can directly drive a 4-ohm, 3–5W speaker without any additional amplifier hardware, simplifying your circuit design considerably.
Q: What size SD/TF card is compatible with this voice module?
A: The module fully supports FAT16 and FAT32 file systems and is compatible with SD/TF cards up to 32 GB in capacity.
