Powering Up!
Before connecting power, get into the habit of checking that there is nothing conductive in
contact that could cause a short circuit with your Raspberry Pi. A quick check that there's
nothing metallic nearby could save you from damaging your Pi!
Plug in the power supply to the bottom left of the Raspberry Pi as shown in Figure 1-12. On
the top-right corner, you should see a green light (labelled
PWR
) come on and another one
(labelled
ACT
) lash.
he Raspberry Pi needs a power supply that can supply 5V 700mA (3.5W). Most decent-
quality mobile phone chargers will work ine - many have the output marked on them, so it's
easy to check. If your power supply can't deliver enough power, your Raspberry Pi may not
start, or it may freeze when it does something computationally more demanding. For more
information, see the “Troubleshooting” section later in this chapter.
