FAQ

Q1: Can the 40-pin ribbon be separated into individual wires?

Yes. Each conductor can be easily peeled away from the ribbon, allowing you to create custom cable groups or use single jumper wires as needed.

---

Q2: Which connector type should I choose?

• Male to Male: Connects two female sockets, such as a breadboard and a module.
• Male to Female: Connects a male pin header to a female socket.
• Female to Female: Connects two devices with exposed male pin headers.

Choose the version that matches your hardware interfaces.
