Specifications
What's in the box
10 colours, 4 of each. Ready to use — no crimping or assembly needed.
Great for
Which type do I need?
- Female-Female (F-F)
Connects two male pin headers together — e.g. Arduino header to sensor module, or sensor to breadboard row.
- Male-Female (M-F)
One end plugs into a female socket (like a breadboard row), the other end has a pin that goes into a pin header. The most versatile type for mixed setups.
- Male-Male (M-M)
Both ends are pins — plug into breadboard holes or female sockets. Used between two breadboards or into female pin headers.
Common questions
Which type should I buy if I'm not sure?
Female-Female is the most commonly needed type for connecting Arduino or ESP32 boards (which have male pin headers) to sensor modules (which also have male headers). Buy a set of each if you're building a general kit.
Will these fit standard 2.54mm headers?
Yes. 2.54mm is the standard pitch for Arduino headers, ESP32 dev boards, Raspberry Pi GPIO, and most sensor/module boards. These fit all of them.
Can I separate individual wires from the strip?
Yes. The wires peel apart easily — just separate them at the housing end. You can use individual wires or keep groups together for tidy cable runs.
Good to know: All three types are in stock. Order multiples of the same type to save per-unit cost. Colour coding: Red is usually 5V, Orange is 3.3V, Black/Brown is GND — not universal but it's the common convention.
