## Description

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 an [SB400](https://core-electronics.com.au/professional-solderable-pcb-breadoard-400-point-one-sided.html) or SB404 Solderable PC BreadBoard to make them permanent.
