This is a Pi 0, a miniature computer that fits in the palm of your
hand—this is Zumi’s brain. It has a microSD card plugged into it,
which is where her memory is stored. Let’s attach a heatsink to
keep Zumi nice and cool.

Powering and Charging
Waking Zumi Up
TIP! Zumi is a computer, so it’s best to shut Zumi o from the
dashboard rather than just flipping the switch o.
You can wake Zumi up by flipping the switch to the right towards the 1position. In
programming, 1means “ON” or “TRUE” and 0means “OFF” or “FALSE.”

Charging When Zumi is OFF
Charging When Zumi is ON
Broken micro USB port?
1 2
Zumi will beep and flash her lights
when her battery is low. When this
happens, you’ll want to charge her
battery.
You can charge Zumi by
plugging the micro USB cable
into her micro USB port, located
where you’d usually find the gas
tank on a car.
You can plug the cable into
an outlet adapter or to your
computer’s USB port.
You’ll be able to tell what her battery
percentage is when she boots up or
from the dashboard.
Zumi can also be charged while she is on. This is very useful for when you’re just
coding and don’t want to drain her battery.
Zumi’s micro USB port may fail after
heavy use. Fear not! You can still
use the Pi 0’s micro USB ports. Lift up
the side window to access the Pi 0’s
micro USB ports.
While Zumi is on, plug in the
micro USB cable.
Flip the switch to the OFF position
(0) to start charging. Think of it
as flipping the switch toward the
micro USB port.
CAUTION! Flip the switch back ON (1) before unplugging, otherwise Zumi
will shut o. Think of it as switching back to battery power, away from the
micro USB port.

Accessing Zumi’s Dashboard
Zumi is accessed through her dashboard, which can be reached by connecting
to her WiFi signal. You’ll need a device that can connect to WiFi, so a computer
with only an ethernet cable won’t work.

Once Zumi wakes up, she’ll tell you her name. Look for her name in your
device’s WiFi list.
Enter the WiFi password, which
is the same as her name.
For example: if her name is
“zumi1234,“ then her password is
also “zumi1234.”
Connecting to Zumi
3Access her dashboard by opening a browser and going to the following
URL. We recommend a laptop running the Chrome browser for the best
experience.

Your computer is connected to Zumi, but Zumi still needs to get online. Even
though she can run oine, we recommend connecting Zumi to the internet so
she can get the latest updates.
Plus, once Zumi is online, your computer will be online too!
Getting Zumi Online
1From Zumi’s dashboard, enter your WiFi information to connect Zumi to
your WiFi.

Once Zumi is online, make sure she is updated to the latest version so you
can get the newest lessons and software updates.
You’re all set! Create a user and sign in. Now you can start exploring
Zumi’s dashboard!
TIP! Zumi can only connect
to 2.4 GHz WiFi networks,
not 5 GHz networks. Most
routers have both, but if yours
doesn’t, you may need to
connect to a dierent network
or use a mobile hotspot to
update Zumi.
