- Signals are accessible at terminal blocks as well as thru-hole pads
- Snap-fit nylon supports (included) ensure the MKR remains in place
- Design allows user to easily add their own DC-DC converter for operation at higher supply voltages
- Includes prototype area
- Mounting Options: Rubber Feet or DIN Rail
- Arduino MKR and DIN rail not included
General Description
The RDBKMKR1 provides a convenient method to connect to an Arduino MKR. Because the Arduino MKR products use long pins and have a cantilever form factor with the USB connector end extending well past the header pins, this RDBKMKR1 breakout board comes with PCB supports to ensure that the Arduino remains secure and properly engages the header sockets. (An application note provides illustrations on an effective technique for inserting the long, thin pins of an Arduino MKR device into the socket headers of the RDBKMKR1 breakout board. See Product Documents section below.)
It is also important to note that the RDBKMKR1 uses socket headers (receptacles) with an improved contact design compared to many typical economical socket headers that use a tuning fork contact design. While tuning fork contacts are well-suited for interfacing with a square pin (25 mils x 25 mils cross section), a tuning fork contact is not designed to interface with thin pins such as those used on an Arduino MKR (25 mils x 10 mils cross section). The socket headers used on the RDBKMKR1 provide a reliable connection even for the Arduino MKR thin pins.
After plugging an Arduino MKR into the socket headers, signals may be conveniently accessed at terminal blocks and/or thru-hole pads. A number of convenient design features, such as a prototype area and pads that accommodate a DC-DC* converter for operation from higher supply voltages, facilitate the inclusion of an Arduino MKR in a variety of projects.
*See app note section for more information. DC-DC converter is not included with RDBKMKR1.
A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", "terminator", or "interface module".

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.
