SB300 Solderable PC BreadBoard, 1 Sided PCB, matches 300 tie-point breadboards, 1.20 x 3.00 in (30.5 x 76.2 mm)
The SB300 Solderable PC BreadBoard enables you to transfer your circuit and wires from a plug-in breadboard without recutting wires or changing your layout.  The SB300 has the same pattern and spacing as a standard 300 connection point solderless plug-in breadboard.  It 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 SB300 has two power rails along the centerline.
