Essential for robotics

Added voice prompts to my line-following robot using this module. It triggers instantly when commanded via serial. The ability to control volume via code is a nice touch.

Perfect for Arduino Projects

This module works flawlessly with my Arduino Uno. The library support is excellent, and setting it up to play sounds from an SD card took less than 10 minutes. Great value for the price.

Works but needs careful wiring

The module works well once connected properly, but the pinout is a bit tight for breadboarding without jumper wires. Ensure you have a stable 5V power source to avoid skipping.

Reliable and Easy to Use

Been using these modules for months in various prototypes. They are stable, handle voltage fluctuations well, and the serial communication is very responsive. Highly recommended.

Great budget option

Does exactly what it says. It's not high-fidelity audiophile gear, but for embedded systems and DIY electronics, it is more than sufficient. The documentation online is plentiful.

Good sound quality, small size

I used this for a custom doorbell project. The audio quality is surprisingly clear for such a tiny board. Just make sure your SD card is formatted correctly to FAT32, or it won't read the files.

5 FAQ

Q: What is the maximum SD card capacity supported?

A: The module officially supports Micro SD cards up to 32GB. Please ensure the card is formatted to FAT16 or FAT32 file system for compatibility.

Q: Can this module play WAV files or only MP3?

A: This module supports both MP3 and WAV audio formats. You can mix them on the same SD card, provided they are in the root directory or organized folders.

Q: Does it work with 3.3V logic boards like ESP32?

A: Yes, the module operates between 3.2V and 5.0V. It is fully compatible with 3.3V logic boards like the ESP32 or ESP8266 without needing a level shifter.

Q: Is a separate amplifier needed for a small speaker?

A: No, this module has a built-in 3W amplifier. You can connect an 8-ohm speaker directly to the SPK+ and SPK- pins. For larger speakers, an external amp would be required.

Q: Can I control playback using buttons instead of code?

A: Yes, you can wire simple push-buttons to the IO pins to control play/pause, next/previous track, and volume up/down without writing any microcontroller code.
