Breadboard - Solderable PCB, 3.75” x 1.85”, Mounting Holes
Solderable PC BreadBoard enables you to transfer your circuit and wires from a plug-in breadboard without recutting wires or changing your layout. This breadboard has the same pattern as a standard 400 connection point solderless plug-in breadboard which has a standard 5-hole strip for each IC pin, just like solderless breadboards. However, it has the advantage that soldered joints provide a more reliable long-term connection than solderless contacts. The board has four power rails like solderless breadboards, plus two bonus rails for power or signals. There are bonus two-hole pads along the centerline allowing DIL (dual in-line) headers to be used as well as a top side silkscreen to position components. Four mounting holes allow your projects to be secured.
