Translucent Solderless Plug-In Breadboard

The transparent breadboard is great for students because the internal connections can be seen. It has a total of 400 connection-tie points (i.e. 400 wire insertion holes), including 4 power rails.

Solderless breadboards are useful 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 transparent/clear 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 and an optional metal back plate is provided.

BPS BreadBoards are Lead-Free and RoHS Compliant.

Finished projects can be moved to a SB400 Solderable PC BreadBoard to make them permanent.
