This large high-quality breadboard is great for prototyping and testing as many circuits as you can think of, it has 5 colour coded screw terminals located at the top of the board for easy connection to a power supply. Each of these terminals can accept a 4mm bannana plug, a Y-terminal or stripped wire.

It has 1mm circular holes in standard DIP spacing arranged on 20 alphanumeric grids, each grid containing 6 columns and 24 rows the board has a total of 3802 holes. Each of the grids snap lock and connect to eachother allowing circuits to be build over multiple grids. All positions are clearly labelled 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 make powering any chips or other devices at a desired voltage extremely easy.

• No soldering needed most parts plug and unplug into the board which means you can reuse all of the parts saving you time and money.
• The interconnected round holes on the board make wiring easier. You can use standard jump wires or any wire AWG # 22-30 (0.3-0.8mm) thickness.
• Dimensions: 346mm * 168mm * 24mm
