Today’s post is about mp3 modules with compact front panels. These devices are used as an audio source (USB/microSD/FM/AUX/Bluetooth) in DIY projects such as portable speakers or to breathe new life into an old music center. Let’s consider audio modules of precisely modest sizes, so as not to take up much space in the project and not spoil the look of old technology.
Consider several popular options for mp3 modules with compact sockets on the AliExpress platform. I bought almost all the models myself, where possible, there will be a link to my articles.
Opens a selection of compact panel audio modules model AVN-757. I used it in this DIY project, it is also on the title photo of the topic. Dimensions 87×25 mm, there is even a small screen with a color indicator.
The panel is powered by 5 V DC, comes with a small remote control and a set of short cables for installation.
- Support for TWS mode (for a pair of modules)

This model is based on the AC6926B chip and supports uncompressed audio tracks in MP3 / WMA / WAV / FLAC / APE formats.

Versions with one appearance differ somewhat in functions, specifically this version with support for Flac and Bluetooth calls (there is a microphone).
The dimensions of the front panel are 108×25 mm.
There are versions of such a module with built-in amplifiers (3 or 25 W per channel), which is convenient for homemade speakers, and simplifies assembly.

The selection is completed by a quality version of the Flac module — TDM156. The front panel size is 115 x 47 mm, there is a 128 x 64 dot screen and a functional encoder for control. Comes with cables and a small remote control.
It’s a folder-navigating device on media, recording, tagging, playing uncompressed track formats, and decent sound.

I hope that the selection of tested compact mp3 modules was useful and you will choose the option that suits your taste and budget.
