There are four kind of Grove cables for different needs. For general
projects using Seeeduino or Base Shield, you can simply use the
standard cables. For projects where you need to connect two I2C devices
by connecting the Grove cable to the I2C port of the main board, you can
use the branch cables. If your project uses two servos, you can choose
Grove – Branch Cable for Servo. If you don’t want to use a Base Shield
or a Seeeduino in your projects, you can choose Grove to 4pin
Female/Male Jumpers, with which you can connect Grove module to
your breadboard directly. Each kind of cable have five different sizes of
length, 5cm, 20cm, 30cm, 40cm, and 50cm.
