Ever wanted a development kit that flies? Well now you can! The Crazyflie is an open source nano quadcopter kit designed for flexible development and hacking. It's among the smallest in the world, weighing only 19 grams and measuring 9 cm motor to motor.
The development platform is open source so schematics and firmware/host source code is available at the Bitcraze website as well as a Wiki with design information and details on how to set up the development environment and get started. It’s designed with development in mind and has an expansion header that enables developers to expand the platform as well as good software development support. Due to it’s small size it’s perfect for developing new software and can easily be flown inside. It can lift a payload of up to 5 - 10 g.
This is the 10 DOF version of Crazyflie that integrate extra sensors for altitude and heading measurement. There is yet no firmware support for these sensors but they have the potential to enable heading and altitude control. If you want to develop a new algorithm or if you want to be able to use some advanced algorithm that might be created for these sensor you should definitely consider the 10-DOF version.
A 2.4 GHz radio chip from Nordic Semiconductors is used for receiving commands and sending telemetry data back to the host computer. The communication with the host is made possible by using the Crazyradio 2.4 GHz USB radio dongle. The Crazyradio can be connected to a PC (with support for Windows and Linux) but also to other hosts that support USB Host or OTG like Android phones.
The Crazyflie Quadcopter is shipped pre-programmed and can easily be wirelessly updated via a radio bootloader from a host PC, so no JTAG is required for reprogramming. For advanced development and debugging there’s also an accessible JTAG interface.
This kit requires soldering skills and is not for beginners. It is not a toy and should be handled with care.
Crazyflie features
Small and lightweight, around 19g and about 90mm motor to motor
Flight time up to 7 minutes with standard 170mAh Li-Po battery
Standard micro-USB connector for charging which takes ~20min for the stock 170mAh Li-Po battery
On-board low-energy radio@1mW based on the nRF24L01+ chip. Up to 80m range (environment dependent) when using the Crazyradio USB dongle
Radio bootloader which enabled wireless update of the firmware
Each part of the Crazyflie Nano Quadcopter Kit is tested before it leaves the factory, but please keep in mind that kit is still experimental, unproven hardware.

can i send a comand to the crazyfile nano with my laptop and let it fly on by itself in a simple straight line without the computer? I have an unusual aplication where the nano flys in one direction wile tethered to a secured pole,,,
Has anyone written code to implement the compass and altitude sensors yet. Where would it be posted if it was out?
A person named Philipp has been working on implementing a hover mode using the pressure sensor - you can find the code at https://bitbucket.org/phiamo/crazyflie-firmware. You'll have to compile the firmware and use the modified client to get it to work but bear in mind it's still very much experimental.

Been there but its not an .exe file. What program do I need to load the modified crazyflie client software (setup.py or setup.sh)?
The camera of the Rpi was released last week,look here:
http://www.raspberrypi.org/archives/3890
is the connector of this quadcopter suitable for this camera?
(it's 3 grams weight).
Unfortunately not - the Pi's camera uses a CSI connector which would be a tight fit on the Crazyflie board. Your best bet is to look for one of the popular micro keychain cameras or one designed for first-person control of RC models.
I had bit of trouble getting it going as well but to me thats part of the fun! I just followed the directions closely and everything worked in the end. I'm running it on XP through Parallels on my Macbook so I'd say it had every reason not to work. The soldering though was a different matter, even with a tiny soldering iron it was a challenge but I'm glad to say the patient pulled through. Well done Bitcraze.... a delightfully challenging project!

Bad experience. Unable to get the USB dongle working. Posting question(s) in the forum just triggered canned suggestions about USB3 vs USB2. Looks like a nice toy to play with, if it one can get it to work. Wasted my money on this and would not recommend it.
