Beyond the clear plastic, this is really just a regular, solderless breadboard. It has 2 power buses, 63 columns, and 10 rows - a total of 830 ties 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 29-20 AWG.
This board also has a self-adhesive on the back. The boards also have interlocking parts, so you can hook as many together as you’d like.
