Quick Overview
The DIYables 2.54mm Jumper Caps are 2-pin shorting connectors designed for the industry-standard 2.54mm (0.1 inch) pitch header pins found on Arduino boards, PCBs, and electronics modules. These shunt caps allow you to short two adjacent pins to configure circuit settings, enabling or disabling features on motherboards, development boards, and custom electronics with a simple plug-and-play action.
Each jumper cap features durable copper alloy contacts that ensure reliable conductivity up to 2A current rating, enclosed in a compact black thermoplastic housing. The housing is heat resistant, supporting operating temperatures from -25°C to +105°C for long-lasting use in a wide range of environments.
This 100-piece value pack is perfect for electronics repair, DIY prototyping, testing, circuit configuration, and bulk usage. Ideal for use with Arduino boards, ESP32, ESP8266, Raspberry Pi, motherboards, custom PCBs, and any device with standard 2.54mm pitch header pins.
