This RJ45 breakout board brings all 8 pins of an 8P8C / RJ45 modular jack out to screw terminal blocks, providing simple and convenient connection to each connector pin. Each pin is also brought to solder pads (3 per line) at 0.1" spacing, allowing the 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.
In addition, this board functions as a buss board, featuring nine 8P8C jacks wired in parallel and connected to the solder pads and the screw terminals. This allows the user to easily break out a connection to screw terminals while at the same time connecting other cables to the same signals via the extra jacks. This is very convenient when "daisy-chaining" several devices together or when wiring multiple devices in parallel. Please see the photo below which depicts the bus connections. Note that all connections are wired 1-to-1 (ie Pin 1 to Pin 1, Pin 2 to Pin 2, etc.).
This break out board is perfect for production wiring, for experimentation and prototype work, and for use in the educational laboratory. It is well-suited for work with RS-232 serial ports, RS-485 networks, sensors, 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".

These breakout boards utilize Straight ("Vertical") connectors. This term refers to the connector itself, denoting that it rises straight out of the circuit board rather than at a right angle. The cable mating to a Straight connector is perpendicular to the PCB, as one can infer from the product photos.
