Short Circuit Jumper 2.54mm

Overview

Short Circuit Jumper 2.54mm is a small but essential component for electronics projects. This tiny cap is designed to slide over two adjacent male header pins, creating a secure electrical connection. Whether you're configuring jumpers on a development board, setting I2C addresses, or enabling/disabling hardware options, this jumper provides a quick and reliable way to modify your circuit without soldering.

Key Features

• Standard 2.54mm pitch: Compatible with the most common header spacing used in electronics.
• Reliable connection: Ensures a solid, low-resistance short between two pins.
• Easy to use: Simply push onto header pins; no tools required.
• Reusable: Can be removed and repositioned multiple times without damage.
• Compact design: Minimal footprint, perfect for dense PCB layouts.
• Durable construction: Made from high-quality materials for long-lasting performance.
