About Kinoma Element
The most important thing to know about Kinoma Element (shown in Figure 1) is
that it is primarily a 3.3-volt system. If you are new to 3.3V systems or to
hardware in general, this means that (unlike with an Arduino or some other
boards), you can only send up to 3.3 volts into input pins on the device without
doing damage to the pin.
