Reliable voice prompter

I used this for a robot that speaks when it detects an obstacle. The latency is very low, and the 'play once' feature ensures it doesn't loop annoyingly. Highly recommended.

Works but needs careful wiring

The module functions well once set up, but the pin headers were a bit loose on my unit. I had to solder them securely. Audio quality is acceptable for voice prompts.

Compact and powerful

Surprised by how loud the 3W output is for such a small board. The button control works instantly without needing complex code. Excellent product for the price.

Good value, clear instructions

Sound quality is decent for a small module. The documentation could be slightly more detailed regarding the wiring diagram, but I figured it out. Works well with 5V logic.

Great for learning embedded audio

Bought this for a university project. It handles MP3 files smoothly. Just make sure your SD card is formatted correctly (FAT32), or it won't read the files.

Perfect for my Arduino project

This module worked exactly as described. I connected it to my Arduino Uno and was able to play sound files from the SD card within minutes. The trigger-once mode is great for interactive displays.

5 FAQ

Q: Does this module support playing multiple tracks sequentially?

A: Yes, you can command it via serial to play specific track numbers in sequence, though the default button mode is set to trigger one file at a time.

Q: Can I power this directly from a 9V battery?

A: No, the operating voltage is 3.3V to 5V. Connecting a 9V battery directly will damage the module. Please use a voltage regulator if using a higher voltage source.

Q: Does it have a volume control feature?

A: Yes, volume can be adjusted via serial commands sent from your microcontroller, allowing you to set levels from 0 to 30 dynamically.

Q: What is the maximum size of the Micro SD card supported?

A: The module supports Micro SD cards up to 32GB formatted in FAT32. Larger capacities may not be recognized reliably.

Q: Is there a library available for Arduino?

A: Yes, several open-source libraries are available on GitHub that simplify serial communication with this module. We recommend checking the DFPlayer Mini compatible libraries.
