Plug and play
Connected it to my ESP32, uploaded the example code, and it worked immediately. The ability to control volume via serial commands is a nice touch.

Good value, minor wiring confusion
The module itself is great and plays MP3s clearly. I lost one star because the pinout diagram on the back was a bit faint, but once I found the datasheet online, setup was a breeze.

Reliable for industrial prototypes
We used several of these in a prototype for an automated guidance system. They have been running continuously for weeks without crashing. The TF card slot is sturdy.

Great for learning embedded systems
As a student, this was perfect for my final year project. It allowed me to add voice prompts easily. The documentation provided by the seller was helpful.

Decent audio quality
For a simple notification sound or background music in a hobby project, this is excellent. Don't expect hi-fi stereo, but for mono announcements, it's more than enough.

Perfect for Arduino Projects
This module works flawlessly with my Arduino Uno. The serial library is easy to use, and sound quality is surprisingly good for the size. Highly recommended for DIY alarms or interactive toys.
Q: Can I power this directly from the Arduino 5V pin?
A: Absolutely. The module operates within a 3.3V to 5V range, so connecting it to the Arduino's 5V output is safe and recommended.
Q: What is the maximum capacity of the TF card supported?
A: The module officially supports Micro SD (TF) cards up to 32GB formatted in FAT16 or FAT32 file systems.
Q: Is there a library available for Python if I use it with Raspberry Pi?
A: Yes, since it uses standard UART serial communication, you can use Python's built-in serial library or community-made wrappers specifically for this chip.
Q: Does this module support playing files from subfolders on the TF card?
A: Yes, the module supports organizing files into up to 30 subfolders, allowing you to categorize your audio tracks effectively.
Q: Does it come with headers soldered?
A: No, the module comes with a separate header pin strip so you can choose to solder them straight or at an angle depending on your project needs.
