Demoboard for the MP3PLAYERUSB player – 16 tracks – Kit

The 20-key keypad gives intuitive control over playback. Of the 20 keys, 16 are dedicated to playing the wanted audio track, while the other 4 keys are reserved for the basic functions of the MP3 module, such as play, stop and volume control.

The audio output is brought out on the SPK contacts, where a loudspeaker can be connected to listen to the voice messages. Alternatively, the stereo jack socket takes headphones for private listening. The JR6001 MP3 module is designed specifically to work from local pushbutton commands, which makes playing audio files simple and intuitive (within the limits of the 4MB memory). That ease of use, together with the ability to play up to 16 tracks, makes the device ideal for applications such as announcements, promotions or spoken instructions in all kinds of settings.

The kit is supplied with assembly instructions. Soldering is required to assemble it.

Note: the power supply and the JR6001 MP3 module (code MP3PLAYERUSB) are not included and must be purchased separately.

• Internal memory: uses an internal 4MB Flash EPROM to store tracks and voice messages, accessible over the USB connection.
• USB interface: connects to a PC over USB and is handled like an ordinary USB pen drive, so files can be loaded without dedicated software.
• Track playback control: handled by four buttons: PLAY, STOP, VOL+ and VOL-.
• Audio outputs: an audio output across the SPK contacts for a loudspeaker, plus a second low-level output on the jack socket for headphones or other stereo applications.
• LED indication: the on-board LED flashes five times to show that the device has started up correctly, stays lit while a track is playing and is off while waiting for a command.

• USB port: microUSB for connection to the PC (it also powers the whole circuit)
