Conductive-thread ribbon cable is the perfect material for wiring wearables because it can be attached just like normal fabric ribbons; it’s flexible, sewable and washable.

You can easily use conductive-thread ribbon cable by connecting it with FFC connectors.

Project Steps

Prepare the components and tools.


conductive thread ribbon cable (can buy from Adafruit / SparkFun)

FFC connectors (0.100’’ pitch, 4pins, male or female) (can buy from Digi-Key)



Understanding the components.

Cut the conductive thread ribbon cable to the length you need.

Cut out the corners at the ends of the ribbon cable so that it will fit into an FFC connector.

Place one end of the ribbon cable between the metal crimping parts of an FFC connector.

Crimp the FFC connector with pliers.

Lock the FFC connector by pressing side edges of the top cover.

Repeat the same to connect the other end of ribbon cable.

Enjoy the conductive thread ribbon cable!

If no current flows through the ribbon cable, check the connectivity of the pins and crimp again.
