Product Overview
A standard 400 tie-point solderless breadboard provides a reusable prototyping platform for assembling and testing circuits without soldering. The central terminal area features 30 rows of 10 interconnected sockets split by a center channel designed to straddle standard dual in-line package (DIP) integrated circuits. Outer power rails on both sides offer dedicated positive and negative distribution buses marked with red and blue polarity lines.
Key Features
- 400 total solderless tie points on a standard 0.1-inch (2.54 mm) grid pitch
- Center terminal strip with 300 contact points organized in 30 rows across columns a-e and f-j
- Dual distribution bus rails providing 100 tie points with color-coded polarity indicator lines
- Center divider sized for standard 0.3-inch DIP integrated circuits
- Interlocking edge tabs and slots for connecting multiple modular boards together
- Peel-and-stick adhesive foam backing for mounting to baseplates or project enclosures
Applications
- Benchtop prototyping of microcontroller and discrete analog circuits before PCB design
- Classroom electronics labs and hands-on circuit demonstrations
- Makers building temporary sensor breakout arrays or custom modular experimenter rigs
- Quick layout and verification of audio modules, test fixtures, and discrete logic circuits
Frequently Asked Questions
What wire gauge works best with these tie points?
The spring contacts accept standard solid-core wire from 22 AWG to 26 AWG, as well as standard 0.1-inch square header pins and flexible jumper leads.
Can multiple breadboards be connected together?
Yes. Molded interlocking tabs and slots along the edges allow side-by-side or end-to-end snapping with matching modular boards.
Does the center channel accommodate standard DIP integrated circuits?
Yes. The center divider separates the two five-pin socket rows by 0.3 inches, allowing standard narrow DIP packages to mount flush across the middle channel with all pins accessible. Larger orders lower the price per piece; the price-break table on this page has the details.
Before a schematic ever touches copper, it earns its proof right here on the bench. Stick it down, run your jumpers, and see if the circuit actually works.
