SparkFun Solderable Breadboard – Large
This is the Large SparkFun Solderable 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 solderable breadboard also includes real estate for screw terminal connectors and a trace down the center gutter for ground.
