USB Hub
Because the Raspberry Pi has just two USB ports available, you will rapidly run out of sockets. The
way to obtain more USB ports is to use a USB hub (see Figure 1-8).

These hubs are available with anywhere from three to eight ports. Make sure that the port supports
USB 2. It is also a good idea to use a “powered” USB hub so that you do not draw too much power
from the Raspberry Pi.
Connecting Everything Together
Now that you have all the parts you need, let’s get it all plugged together and boot your Raspberry Pi
for the first time. Figure 1-9 shows how everything needs to be connected.

Insert the SD card, connect the keyboard, mouse, and monitor to the Pi, attach the power supply,
and you are ready to go.
