General Description

These RJ45 breakout boards bring all 8 pins plus shield of a shielded 8P8C modular jack out to screw terminal blocks for easy connection and prototyping work. The connection from the jack's shield is connected to a copper plane on the bottom side of the PCB in addition to being brought out to a screw terminal. Each pin, including the shield, 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 RS-232 serial ports, data acquisition equipment, and any other device that uses an RJ45/8P8C connector. It can be helpful in making MODBUS connections. A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", "terminator", or "interface module".

For those working with ethernet networks, please note that this board is not CAT5 certified. However, our experience so far shows that these boards can be used on 100Mbps ethernet networks without introducing problems. As usual, the wires you connect to the breakout board's screw terminals should maintain their twist as close to the screw terminals as possible.

Connector Style

These breakout boards are available with either a Right Angle connector or a Straight ("Vertical") connector. The terms Right Angle and Straight refer to the connector itself, NOT the relationship of the mating cable to the plane of the PCB. In fact, the cable mating to a Right Angle connector is parallel to the PCB, while the cable mating to a Straight connector is perpendicular to the PCB.

There is a slight difference in board dimensions between the Right Angle and the Vertical options.

  • BRK8P8CSJ-R: 2.38" x 2.3"
  • BRK8P8CSJ-S: 2.30" x 2.0"

Mounting Options

These products are available in two different mounting variants. Product numbers ending with -DIN come with DIN clips already installed and ready to snap onto 35mm or 32mm DIN rail. Product numbers ending with -FT have stick-on rubber feet installed on the bottom side, allowing for benchtop use or panel mounting. For panel mounting, we suggest 1/4" nylon standoffs under the mounting holes, and #6 screws.
