Getting started with the Crazyflie
2.0
Unpacking the Crazyflie
The Crazyflie 2.0 packet contains the following items. Make sure that you have all of them
before you start assembling.
package contents
1 x Crazyflie 2.0 control board with all components mounted
5 x CW propellers
5 x CCW propellers
6 x Motor mounts
1 x LiPo battery (240mAh)
5 x Coreless DC motors
2 x Short expansion connector pins (1×10, 2mm spacing, 8 mm long)
2 x Long expansion connector pins (1×10, 2mm spacing, 14 mm long)
1 x Battery holder expansion board
Testing
The Crazyflie 2.0 is tested extensively in the production, but to make sure nothing has
happened during shipping/storage you should run the tests before starting the assembly.
Power on the Crazyflie 2.0 using a USB source (either computer or charger) and check the
results of the test below. Note that it’s important to hold the Crazyflie 2.0 steady during the
test and away from strong magnetic sources.
self-test
Before you start assembling anything, run the power on self-test by connecting the Crazyflie
2.0 to a uUSB power source. The LEDs M1 and M4 will indicate the result of the test. If the
M4 LED blinks GREEN five times fast, then the test has passed.

self-test fails
If the self-test fails, then the M1 LED blinks 5 times fast RED, then pauses and does it again.

Assembling your Crazyflie 2.0 will probably take less than 10 minutes, but there are a few
pitfalls. So make sure to follow the instructions below!
twisting the wires
Start by twisting the wires of the four motors. This will reduce electronic noise and make the
wires fit better in the motor mount “hooks”.
mount the motors
Push the four motors into the motor mounts. You will need some force to insert them. If it is
difficult doing it as in the video try putting the motor can towards a table edge and press on
the mount, however don’t press on the motor axis while inserting them as it might damage
the motor. The motor should be inserted all the way to the stop in the mount.

attach the twisted wire
Attach the twisted wire into the two small “hooks” that are underneath the motor mount.

Insert the motor mounts on the Crazyflie 2.0 wings. They are press fit and might need a
small amount of force. Make sure they go all the way to the stop. It’s not important which
motor you put where. After it’s been inserted, connect the motor connectors to the Crazyflie
2.0.
attach the propellers
Now it’s time to attach the propellers. Note: There are two kinds of propellers, the clock wise
(CW) and counter clock wise (CCW) propellers, each kind has their own bag in the box.
Here we are attaching the CW propellers.

Here’s a detailed view of where to attach CW and CCW propellers.
attach the rubber pad
The rubber pad should be attached to the Crazyflie 2.0 between the expansion headers.
This will create friction, keep the battery from slipping out and also protect the electronics.

There are two types of headers in the box, long and short ones. Find the two short ones and
insert them into the expansion connector.
attach the battery
Place the battery between the headers inserted into the expansion connector and insert the
battery holder board onto the headers. Watch out for the pins that can be a bit sharp when
inserting it. The friction should hold the battery in place so tighten it until it does.
Now connect the battery and you are finished with the assembly. The battery wires can
preferably be bent and placed underneath the PCB to be out of the way.

power on!
The assembly is finished, now it’s time to power it on! Note that the power button is a push
button, not a sliding button. During the power-on self-test all the propellers will spin in
sequence. Make sure they all spin, if they don’t then check the motor connections.
getting to know your Crazyflie
First of all, lets look at what is front and back, this is important when flying and also when
mounting expansion decks. The small “bump” (the antenna) is on the front and the blue
LEDs are at the back.

Start up sequence
When the Crazyflie 2.0 is powered on it will automatically go through a short sequence of
events to get ready for flight.
1. Run self tests - the Crazyflie 2.0 checks that the hardware is OK
2. Calibrate sensors - the Crazyflie 2.0 reads its sensors to get base values. It must be
absolutely still to do this, so it’s best to put it on a level surface for a second.
3. Ready to fly!
Understanding LEDs
You also need to understand what the LEDs mean.
Power on and all is good: The blue LEDs (2 and 3) are fully lit and the front right LED
(1) is blinking red twice every second.
Power on and all is good but sensors are not yet calibrated: The blue LEDs (2 and 3)
are fully lit and the front right LED (1) is blinking red with 2 seconds interval. Put the
Crazyflie 2.0 on a level surface and keep it absolutely still to calibrate.
Radio connected: The front left LED (4) is flickering in red and/or green.
Battery low: The front right LED (1) is fully lit in red. It’s time to land and re-charge the
battery.
Charging: The back left blue LED (3) is blinking while the right back blue LED (4) is lit.
Boot loader mode: The blue LEDs (2 and 3) at the back are blinking approximately
once every second.
Self test fail: The right front LED (1) is repeatedly blinking five short red pulses with a
longer pause between groups.
