This item has been retired but if you still require a small affordable breadboard we'd suggest the Breadboard Deluxe.
This small, compact, high-quality breadboard is great for prototyping and testing circuits. It has 1mm circular holes in standard DIP spacing arranged on 5 alphanumeric grids, each grid containing 6 columns and 24 rows the board has a total of 948 useable holes. The AD-01 can snap lock and connect to other AD breadboards allowing circuits to be built over multiple boards. All positions are clearly labeled and at the end of every grid, there are the two power rails, RED and BLACK that can be connected to the corresponding terminal connections at the top of the board. This makes powering any chips or other devices at the desired voltage extremely easy.
Please Note: This board does not come mounted to a base like many of the other AD breadboard models.
