The GL12 is an 840-point solderless breadboard, the kind of prototyping tool that lets a circuit be built, tested and modified without ever picking up a soldering iron. Its main working area has 840 tie points, arranged as 128 groups of five connected terminals, plenty of room for a moderately involved circuit with several ICs, resistors and other components.
Alongside the main grid, 8 bus lines run along the edges with 25 connected terminals each, typically used for power and ground so that supply wiring stays separate from signal connections and is easy to trace visually.
Hole spacing follows the standard 2.54mm pitch, which matches the pin spacing of most common through-hole components, headers and jumper wires, so parts plug in without any awkward fit. The board accepts transistors, diodes, LEDs, resistors, capacitors and similar components directly, and works with jumper wires around 0.8mm in diameter.
A self-adhesive back lets multiple breadboards be joined together to build a larger prototyping surface for bigger projects, and because nothing is soldered, both the board and every component used on it stay completely reusable afterward.
Students, hobbyists and anyone in the early design or testing phase of a circuit will find this a standard, dependable prototyping surface, useful right from a first Arduino experiment through to more involved multi-component builds.
840, arranged as 128 groups of five connected terminals.
Standard 2.54mm.
Yes, the self-adhesive back allows multiple breadboards to be spliced together.
Jumper wires around 0.8mm in diameter fit the holes well.
Yes, since nothing is soldered, both the board and its components can be reused for other projects.
