The yampp Industrial III (YI3) is the newest commercial MP3 player based on the yampp series of MP3 players.

The yampp Industrial III, is like is sister card, the yampp Industrial, mainly intended as a replacement for mechanical playback units such as Cassette Decks or CD-ROMS.
The mechanical nature of these devices often makes them slow and/or unreliable and require regular maintenace or replacement. The yampp Industrial III is a complete Solid-State design, with no moving parts, offering high reliability and reducing maintenance to an absolute minimum.

The player firmware has an extensive command set, which makes it highly flexible. A few features like autostart e.t.c. allows it to be used autonomous in some environments, but it's mainly intended for being controlled by an external controller.

The player can be controlled via the serial port. The communication standard is like normal RS-232, but at 3.3V level with active low signalling.

Compared to the yampp Industrial, it's physically smaller, but at the expense of the digital control inputs and the power supply.

However, it has a completely new firmware, making it compatible with the command set used by Quadravox players, making it easy to replace these.

The YI3 has the following features :

• Small size, only 50x60 mm. Card protruding 14 mm on long edge.
• High quality 4-layer PCB for low EMI.
• CompactFlash card based. Using standard PC formatted FAT16 cards. Card can be up to 4GB, allowing more than 70 hours of continuous, unrepeated near CD quality music (at 128 kbps).
• Easy and fast firmware upgrade through a file on the CF card.
• Serial asyncronous interface for remote control of the player (Like RS-232, but at 3.3V levels).
• BUSY status output line.
• Flexible 4-15V DC supply voltage.
• Line level output for connection to an external amplifier.
• Low power consumption. Approx. 40 mA (operating, with Sandisk 128 MB card).
• Plays all MP3 bitrates up to and including 320kbps.
