General Description

This breakout board brings all 4 pins of its 4P4C modular jack out to screw terminal blocks for easy connection and prototyping work. Each pin is also brought to solder pads (5 per line) at 0.1" spacing, allowing easy addition of standard pin headers. Please note that the breakout boards are manufactured with a connection between each connector pin and the corresponding terminal block position; no soldering of any type is necessary. The solder pads simply provide an area for making optional connections to additional headers or other components.

This break out board is perfect for experimentation and prototype work, as well as for use in the educational laboratory. It is well-suited for work with serial ports, data acquisition equipment, telephone equipment, and any other device that uses a 4P4C connector. A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", or "interface module".

The 4P4C designation on the modular jack stands for 4-Position, 4-Conductor, meaning it will accept telephone connectors sometimes referred to as RJ9 or RJ-9 (although it isn't truly an FCC Registered Jack type). On a telephone, the 4P4C connector is used for the handset.
