NuoTo YX5300 UART MP3 module 5-pack barebone mini PC

SKU CH-9FEF-WD1J0

Five UART-controlled MP3 modules with TF card slots play MP3 and WAV files at sampling rates up to 48 kHz and offer 30 volume levels

  • Plays MP3 and WAV files for versatile audio
  • 30 adjustable volume levels suit any environment
  • UART TTL control at 9600 bps simplifies integration
  • Supports micro SD and SDHC cards for storage
  • Operates on 3.3 V or 5 V logic levels

Five-module voice pack

This pack contains five YX5300 UART MP3 modules for adding audio playback to microcontroller projects. Each board includes a TF card slot for micro SD or micro SDHC storage and supports MP3 and WAV files. The modules accept 3.3 V or 5 V TTL power and communicate at 9600 bps over a serial port. Volume is adjustable across 30 levels.

Replaces discrete audio shields

These modules replace separate MP3 decoder chips, SD-card interfaces and level-shifting circuitry on a single board. The jump is worth it when you need multiple identical nodes for voice prompts, alarms or navigation cues without wiring individual components each time.

Suits Arduino, AVR, ARM and PIC builders

Makers adding spoken alerts to robots, vehicles or industrial equipment will find the simple serial command set fast to integrate. Developers who require higher-fidelity output, stereo decoding or wireless streaming should look at other solutions.

Questions about this item

Does the module have a built-in slot for a micro SD card?

Yes, an on-board TF card slot accepts micro SD and micro SDHC cards for audio storage.

What baud rate and voltage levels does the UART interface use?

UART TTL serial control runs at 9600 bps with 3.3 V or 5 V logic levels.

When would the TF card need to be replaced?

Replace the card if it fails, becomes corrupted, or you need more space for MP3 or WAV files.
