This is a new electronic device, integrating both a MP3 player and an audio recorder inside. The supported algorithms for coding and decoding are: the now ubiquitous MP3 format and his direct competitor (and a royalty-free one), Ogg Vorbis. Everything has been thought so that each component needed for the operations is housed on a printed circuit having a limited size of about 25 x 40 mm.

This last one is supplied with a 15 pins angle header (Break Away Header), with 2,54 standard pin spacing, making it suitable for a vertical insertion in a breadboard, or for a combined usage with another printed circuit. The connector allows insertion and removal, as opposed to a dual female header, or to the permanent cabling in the case you prefer to weld the device to the hosting project.

The circuit supplies a microSD Push-Pull slot inside, operating as mass memory, and dedicated to the archiving of the recorded audio fluxes or as a support to the playback of musical tracks. Moreover, the circuit has all the components needed for the operations inside, thus it is enough to give a power supply tension and to select the interaction mode so that, in a short time, it is possible to hear your favourite track or to start a short or long term recording.
