PCB Description: The ProtoBoard-2H-1 prototyping circuit board has 2-hole pre-cut strips. The convenient 2-hole ProtoBoard pattern provides an easy way to connect parts while maximizing usable board area. ProtoBoard-2H is a good pattern for compact circuit layouts, and it is often more convenient than pad-per-hole patterns. It is good for analog use as well as digital since many discrete components can be located closely. It is a single-sided board with holes on 0.1" centers. An anti-tarnish coating protects the copper for a long shelf-life and provides easy soldering. Enclosure Description: The BOX1-1455C is an extruded aluminum enclosure for electronic projects. The enclosure is designed for BusBoard Prototype Systems size 1 prototype PCBs (50x80mm boards). PC boards mount horizontally by sliding into 4 built-in card guide slots. Two aluminum end panels are provided with attractive plastic bezels to hide the seams. The screws are recessed flathead type to provide a flat surface. The silver aluminum is clear anodized for protection from the elements. The end panels can be removed for easy drilling or cutting of holes. Screws and adhesive rubber feet are included.
