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.
