Compatibility and Common Applications

The Breadboard GL-12 is compatible with a wide range of components and development boards that use standard 2.54 mm spacing. Typical uses include:

• Prototyping with Arduino, ESP32, Raspberry Pi add-on circuits and other microcontrollers
• Sensor interfacing and small embedded systems
• Educational electronics labs and hands-on learning
• Testing logic circuits and analog signal experiments
• Temporary wiring for debugging and development

Mounting, Expansion and Practical Tips

• Use the self-adhesive backing to fix the breadboard to project enclosures and work surfaces.
• Fasten using the mounting holes when a more permanent or rugged installation is required.
• Combine multiple GL-12 boards using the snap-together feature to scale your prototyping area.
• Place power rails near your most-used components to reduce jumper clutter and improve organization.
• For reliable connections, use clean jumper wires and avoid bending component leads excessively.
