Breadboard-830t is a translucent solderless (plug-in) breadboard. The transparent breadboard is great for students because the internal connections can be seen. It has a total of 830 connection-tie points (I.E. 830 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 BB830 has a 630 tie-point ic-circuit area Plus four 50 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 peel able 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 BR1 sold ER able PC breadboard to make them permanent.
