The Universal 4 Pin Buckled Cable is made for the Grove System to connect all of the Twigs to the Stem - Basic Shield or to other Twig compatible boards for quick prototyping. As a lot of users ask for different length of cables, so we made the 5cm,20cm,30cm,40cm,and 50cm cables for different applications.

More information about how to choose a cable, please refer to this manual.
