These breakout boards bring all 50 pins and shield of a 50-pin Centronics connector out to double deck screw terminal blocks for easy connection and prototyping work. In addition to the screw terminal connection, each pin is also brought to solder pads (3 per pin) at 0.1" spacing, allowing the addition of small components or 0.1" headers. This 50-pin Centronics connector is also referred to as a CHAMP, Amphenol, 50-pin telco, or RJ-21 connector.
These break out boards are perfect for experimentation, prototype work, lab projects, and permanent installations. They are well-suited for interfacing with data acquisition equipment, phone systems, or any other devices that use the RJ-21 50-pin Centronics connector. A breakout board is sometimes referred to as a "transition module", "terminal board", "breakout box", or "interface module".
