Perfect for prototyping audio projects
This development board works exactly as described. The pinout is clearly labeled, and it integrated seamlessly with my custom MP3 player project. Fast shipping too!

Good quality, minor documentation gaps
The hardware quality is excellent and stable. I deducted one star because the included datasheet was a bit brief on the advanced register settings, but online forums helped.

Great for university projects
Used this for my final year embedded systems project. It's robust, easy to solder, and the power consumption is very low. Arrived in two days.

Reliable component for stands
Bought this to upgrade an old MP4 stand mechanism. The MICROMODULE HDK handles high-bitrate files without skipping. Highly recommended for DIY electronics.

Solid performance
Works well for decoding various audio formats. The form factor is compact which fits perfectly into our custom enclosure designs. Would buy again.
Q: Can this be used with a 3.7V Li-Ion battery directly?
A: Yes, the board operates within a 3.3V to 5.0V range, so a standard 3.7V Li-Ion battery is compatible. However, we recommend using a protection circuit for safety.
Q: What is the maximum sampling rate supported?
A: The MICROMODULE HDK supports sampling rates up to 48kHz for standard MP3/WAV files and up to 96kHz for high-resolution FLAC playback.
Q: Does this board support Bluetooth connectivity out of the box?
A: No, the 54-00028 is a dedicated decoding development board. You would need to interface it with a separate Bluetooth module via the UART pins for wireless functionality.
Q: Is a programming cable included in the package?
A: The package includes the development board and pin headers. A USB-to-UART programmer cable is sold separately and is required for firmware updates.
Q: Do you provide sample code for Arduino integration?
A: Yes, sample libraries and code snippets for Arduino and STM32 platforms are available for download on our official GitHub repository linked in the user manual.
