GL-12 840 Points Solderless Breadboard for Prototyping

GL-12 840 Points Solderless Breadboard – For Electronics Prototyping

The GL-12 840-Point Solderless Breadboard is a full-size prototyping board that provides ample space for building and testing complex circuits without soldering. With 840 tie points arranged in standard 2.54mm pitch rows, it accommodates DIP ICs, through-hole components, and all standard development board modules.

Key Specifications

• Total Tie Points: 840
• Terminal Strip: 63 rows × 10 columns (split into two halves)
• Bus Strips: 4 power rails (2 per side)
• Pitch: 2.54mm (0.1") standard
• Body Material: ABS plastic (flame retardant)
• Contact Material: Phosphor bronze with nickel plating
• Dimensions: ~165mm × 55mm
• Adhesive Base: Self-adhesive backing for mounting

Compatibility & Use Cases

This breadboard is compatible with all standard through-hole components and development boards including Arduino UNO, ESP32, NodeMCU, Raspberry Pi Pico, and sensor modules. Common applications include:

• Rapid circuit prototyping without soldering
• Testing and debugging sensor and actuator circuits
• Building power supply and voltage regulator circuits
• IC-based circuit design (555 timer, op-amps, logic gates)
• STEM and educational electronics project builds

The interlocking design allows multiple breadboards to be joined side-by-side for larger circuit builds.

Frequently Asked Questions

How do the holes connect internally?
Each column of 5 holes in the main area is connected together vertically. The long red and blue rails on the sides run horizontally and are meant for power and ground. The centre gap separates the two halves so you can plug in DIP ICs like the LM555.

Do the power rails run all the way down the board?
On full-size boards like this, the rails are often split halfway. Bridge the two halves with short jumper wires near the middle so power reaches the entire rail.

Which wires should I use with it?
Male-to-male jumper wires or 22 AWG solid-core wire fit the contacts perfectly. Female-ended wires do not plug into a breadboard.

Can I mount it permanently?
Yes. Peel off the backing to reveal the self-adhesive base and stick it onto your project box or workbench. Boards also interlock side by side when you need more room.
