Solderless Breadboard GL-12 (840 Tie Points)

Description

The Solderless Breadboard GL-12 is an absolute necessity for anyone venturing into electronics, whether you are a professional engineer testing a new schematic or a student learning basic circuit design. Solderless breadboards allow you to quickly plug in, remove, and swap components without the need for a soldering iron, making the prototyping phase fast, safe, and completely reusable.

Available at Tomson Electronics, the GL-12 model provides a substantial prototyping area with a total of 840 tie points. The central component area is divided into 128 groups of 5 connected terminals, perfect for mounting standard DIP integrated circuits and microcontrollers. Along the edges, it features 8 independent buses of 25 connected terminals to easily distribute power and ground connections. With standard 2.54mm (0.1") pitch spacing, it perfectly accommodates jumper wires, resistors, LEDs, and modern microcontroller boards.

Frequently Asked Questions (FAQ)

Q: How are the holes connected internally?
A: In the main central area, the terminals are connected vertically in groups of five (128 groups total) separated by the center gap. The red and blue power rails running along the top and bottom act as 8 independent buses of 25 connected terminals to easily distribute power where needed.

Q: What is the gap down the middle of the board for?
A: The center channel is perfectly sized for DIP (Dual In-line Package) integrated circuits. When you place a microchip across the gap, the pins on the left side are electrically isolated from the pins on the right side, preventing a short circuit while giving you 4 active tie points on each side to wire to the chip.

Q: My circuit is too big for one board. Can I combine them?
A: Yes! The GL-12 breadboards have small interlocking tabs and slots molded into the plastic sides. You can slide two or more boards together to expand your 175x67mm workspace into one massive prototyping surface.
