A two-pack of our popular ProtoBoard2H-2 prototyping board! The ProtoBoard-2H-2 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.
