PCB jumpers, also known as configuration links, are essential components that provide flexible circuit routing and configuration options on printed circuit boards. These compact connectors allow designers and technicians to easily modify circuit paths, enable or disable functions, and configure hardware settings without requiring circuit modifications or component replacement.
Key Features
Multiple Configuration Options – Available in 2-pin, 3-pin, and multi-pin configurations to accommodate various switching and routing requirements. Standard pitch options include 2.54mm (0.1″) and 2.0mm spacing.
Durable Construction – Manufactured with high-quality materials including gold-plated contacts for reliable electrical connection and corrosion resistance. Robust plastic housings ensure secure fit and long-term durability.
Easy Installation – Simple push-on design allows for quick installation and removal without special tools. Color-coded options available for easy identification and organization.
Low Profile Design – Compact form factor minimizes board space requirements while maintaining secure electrical connections. Available in both vertical and right-angle orientations.
Applications
Perfect for development boards, prototyping circuits, embedded systems, and production hardware requiring user-configurable options. Commonly used for setting baud rates, selecting operating modes, enabling debug features, or configuring I/O options.
