YS-M3D5T Triggered MP3 Voice Playback Module
Add a triggered message to a DIY display or interactive project. The YS-M3D5T module plays MP3 or WAV files through compatible audio hardware. It is for makers arranging physical triggers rather than writing a complete audio system.
- ✅ Give different triggers different messages — Nineteen input ports map to separate audio files.
- ✅ Choose a playback behaviour — Single, loop and hold-to-play modes suit different interactions.
- ✅ Adjust the sound locally — Function ports provide playback and volume controls.
- ✅ Use your own recordings — MP3 and WAV playback let you choose the content.
Build the message around the interaction
Use the module for a recorded greeting, exhibit response or a small product demonstration. Arrange the trigger and file naming to suit the chosen playback mode; the specified layout uses folder 01 and files 001.MP3 through 019.MP3.
A suitable 3.7–5.5V supply and compatible speaker are required. The stated input current requirement is at least 300 mA with a speaker. Storage is supported up to 32GB, but a card and speaker are not confirmed as included.
