Electronics hobbyists and makers, this Gikfun connector set is exactly what you need for all your wiring projects! You get 100 female pin connector terminals and 100 male pin connector terminals - that's 200 pieces total, which should cover pretty much any project you have in mind. These are designed specifically for Dupont jumper wires and fit standard 2.54mm connector housings perfectly. The male pins work with 21awg wire, making them versatile for various applications. The quality is solid - good plating prevents corrosion, and the retention tabs work properly to secure wires in place. Perfect for Arduino projects, Raspberry Pi setups, custom cables, prototyping, or repairing existing wiring. Whether you're building robots, custom controllers, or just need to make some custom cables, these connectors make the job so much easier. The bulk quantity means you won't run out mid-project, and having both genders available lets you create complete cable assemblies. Great for automotive projects, electrical appliances, medical devices, and internet of things applications. The precision manufacturing ensures consistent fit and reliable electrical connections. A must-have for any electronics workbench - once you start using proper connectors instead of just twisting wires together, you'll wonder how you managed without them. Keep them organized in a small parts container and you'll always have the right connector when you need it.
