Compatibility
This breadboard works with any through-hole components and standard 2.54 mm pitch connectors. It is compatible with popular development boards like Arduino Uno, Mega, Raspberry Pi, ESP32, and STM32. The four power rails simplify voltage distribution for mixed 3.3V and 5V circuits.
Wiring Notes
Use 22 AWG solid core jumper wires for secure connections; stranded wire may fray and cause shorts. Connect power to the outer rails and bridge them with short wires if needed. For DIP ICs, place them across the center groove to avoid pin shorts.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, the standard 0.1-inch pitch matches Arduino headers perfectly. You can directly plug in an Arduino Uno and use the breadboard for prototyping.
Does it have an adhesive backing?
Yes, the GL-12 breadboard includes a peel-off adhesive foam backing for mounting on surfaces, though some users prefer to secure it with screws for permanent setups.
What is the current rating per tie point?
The phosphor bronze contacts can handle up to 1A per tie point, but for high-current circuits, use external wiring to prevent heating.
