BreadBoard-400 is a solderless (plug-in) breadboard with 400 connection tie-points (i.e. 400 wire insertion holes). It has 4 power rails. Solderless breadboards are great for building and testing new circuits because parts can be easily inserted and removed. They are completely re-usable. The BB400 has a 300 tie-point IC-circuit area plus four 25 tie-point power rails. The housing is made of white ABS plastic, with a printed legend giving numbers and letters for columns and rows. The internal contacts are phosphor bronze with a plated nickel finish. A peelable adhesive tape backing is provided for attaching it to a surface. BPS BreadBoards are Lead-Free and RoHS Compliant. Finished projects can be moved to a SB400 or SB404 Solderable PC BreadBoard to make them permanent.

The SB404 Solderable PC BreadBoard enables you to transfer your circuit and wires from a plug-in breadboard without recutting wires or changing your layout. The SB404 has the same pattern as a standard 400 connection point BB400 solderless plug-in breadboard. It has a standard 5-hole strip for each IC pin, just like solderless breadboards plus 4 power rails. However, it has the advantage that soldered joints provide a more reliable long-term connection than solderless contacts. The SB404 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. A top side silkscreen helps to position components. Four mounting holes allow your projects to be secured. BPS prototyping boards use high-quality FR4 glass epoxy PCBs for long life. An anti-tarnish coating protects the copper for a long shelf-life and provides easy soldering. BPS boards are lead-free and RoHS compatible.
