MOTG-MP3

MOTG-MP3 is an audio sound module that can play MP3 audio files stored on a micro-SD card, such as voice and music.

The MOTG-MP3 features an on board 16bit MCU, specifically designed for hardware audio decoding by 4D Systems.
It features an on-board mono amplifier capable of driving a 4-ohm 3-watt speaker. It also features stereo DAC output for connecting directly to headphones or to an external amplifier.

In short, the MOTG-MP3 offers very flexible, compact and low cost embedded audio solution for many applications.

About Modules on the Go (MOTG)

MOTG, Modules on the Go is a concept from 4D Systems revolutionizing embedded design allowing instant and flexible hardware expansion solution.

MOTG modules offer a simple plug and play interface to Universal MOTG BUS (UMI) allowing rapid assembly and maintenance. This removes the hassle of having to solder and end up with a wiring nest. It also allows the designer to easily remove the existing module or add another module instead, which could be very useful during the phase of prototyping.

Importantly, MOTG series was designed with careful consideration for space with its compact and low profile design.
