This white solderless breadboard has two power buses, 30 columns, and 10 rows — a total of 400 tie-in points. All pins are spaced by a standard 0.1". The two sets of five rows are separated by about 0.3", perfect for straddling a DIP package over. The board accepts wire sizes in the range of 29-20AWG, but be warned that a large gauge like 20AWG may permanently bend the contacts.

The board has an adhesive backing and measures 82 × 52 × 10 mm. An interlocking design allows you to hook together as many as you'd like.
