200PCS Jumper Caps Kit 2.54mm | Arduino Raspberry Pi PCB

200-Piece Mixed Jumper Caps Kit – 2.54mm Pitch for Arduino, Raspberry Pi & PCB Projects

Take the guesswork out of your next electronics build with this comprehensive 200-piece mixed jumper caps kit. Designed for the standard 2.54mm (0.1-inch) pitch pin header connector, these caps are essential for every maker, hobbyist, or engineer working with Arduino boards, Raspberry Pi, breadboards, or any PCB that requires reliable short-circuit bridging.

The kit includes both standard open-style caps and long-handle caps across five vibrant colors — Black, Red, Yellow, Green, and Blue — making color-coded circuit organization effortless. With phosphor bronze contacts plated in gold-over-nickel and a UL94V-0 rated polyester insulator, these caps deliver solid electrical connection and durability for low-voltage applications up to 48V.

Made in Mainland China.

Frequently Asked Questions

Q: What pitch size are these jumper caps, and will they fit my Arduino or Raspberry Pi?

A: These jumper caps are designed for the standard 2.54mm (0.1-inch) pitch pin header connectors, which is the universal standard used on Arduino, Raspberry Pi, ESP32, and the vast majority of hobbyist and professional PCBs. They should fit your board's pin headers perfectly.

Q: What is the difference between the open caps and the long-handle caps in this kit?

A: Both types perform the same electrical bridging function. The standard open caps sit flush against the board for a low-profile connection, while the long-handle caps feature an extended body that makes them much easier to grip, insert, and remove — especially useful on densely populated circuit boards where space is tight.

Q: Are these jumper caps compatible with motherboard BIOS/CMOS jumpers?

A: Yes! The 2.54mm pitch is also the standard used on PC motherboard jumpers for settings like CMOS reset, boot mode selection, and other hardware configuration options. These caps work seamlessly in those applications as well.

Q: How are the 200 pieces divided among colors and styles?

A: The kit is evenly divided: you receive 20 pieces each of Black, Red, Yellow, Green, and Blue in both the standard open style and the long-handle style — totaling 100 standard caps and 100 long-handle caps across 10 color/style combinations.
