Breadboard 170 is a solderless (plug-in) breadboard with 170 connection tie-points (i.e. 170 wire insertion holes).
Solderless breadboards are great for building and testing new circuits because breadboard jumper wires can be easily inserted and removed.
The housing is made of white ABS plastic, with a printed legend giving numbers and letters for columns and rows，2-sided peelable adhesive tape.
The internal contacts are phosphor bronze with a plated nickel finish.
Be used for Arduino breadboard.
