General Description
Make connections quickly and reliably with this breakout board, which brings every pin of its male dual row header connector out to screw terminals. The header connector has pins spaced at 2mm pitch.
Each pin is also brought to solder pads (3 per pin) at 2mm spacing, allowing easy addition of pin headers or other components. 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.
The header connector on this breakout board comes standard with long ejector latches. "Long ejectors" indicates that the ejectors are the correct length to accomodate IDC connectors with strain reliefs installed.
This breakout board is perfect for production applications as well as experimentation and prototype work. It is well-suited for interfacing with microcontroller programming circuits, I/O ports, DAQ equipment, and any other device that uses a 2x20 40-position, 2mm pitch header.
A dual row header is sometimes referred to as an "IDC Header", "IDC connector", or "ribbon cable connector". A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", "terminator", or "interface module".
Note: The Raspberry Pi does NOT use the 2mm header pitch. Instead, please see our BRK2X20 board series.

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.Product Details
