SparkFun Solder-able Breadboard - LargeSparkfun
This is the Large Solder-able Breadboard. A bare PCB that is the exact size as our full-size breadboard with the same connections to pins and power rails. This board is especially useful for preserving a prototype or experiment you just created on a solderless breadboard by soldering all the pieces in place.
The large solder-able breadboard also includes real estate for screw terminal connectors and a trace down the center gutter for ground.
