I just wana look how small i can build one with only one layer

ok, so that is 2x2cm^2? Small form factor would help for my small 250 heli.

Hi,
it is 2,5x2,7 cm .. with dual layer 2x2 should be possible

how do you fix it to the frame
with foam tape ?

yes something like that
just if someone want to build it .. i found a small mistake on it
pin 1 of the MPU should be connected to GND ..
i will fix this soon.

the arduino part if it works
and the MPU is ordered..
there was also a bug with the cristal pins .. so i need to solder it with wire .. in this new version this is fixed

Looks really nice. I do not see any level converters in your design. Is MPU6050's i2c pins 5v tolerant?

Hi,
it works fine in this setup. it is powerd by 3.3v with 2,2k 3,3v pullups.

Hello I have a question about this board.
I did the same one, but I can not connect it to my PC.
It is defined as Arduino Leonardo , but it does not work as COM port because I need a special driver for PC to work with Arduino Leonardo (ATmega32u4).
Maybe I did something wrong during installation bootloader for Arduino Leonardo board in Arduino IDE.
Please can you tell me how to get started with this board?

Hi,
you will need to install a driver for it..
one is in arduino/drivers
another is from sparkfun:
http://dlnmh9ip6v2uc.cloudfront.net/dat ... Driver.zipthere is also a tutorial:
http://www.sparkfun.com/tutorials/338can we see a image of your 32u4 board?

Hi Felix,
the Board looks very nice!
It's the same thing I busy myself the last days. I want to use the pin compatible MPU-9150 which is available next month.
Did you flash the Arduino bootloader over USB with "Flip"?

Jan

Thanks, I tried to program my ATmega32U4 as Leonardo and Pro Micro and install the appropriate drivers, but the driver is not installed correctly on my PC.
I do not understand what the problem is, I did everything according to instructions on the links.
Here is my image of my board

Hi ABC,
this tutorial (
http://www.sparkfun.com/tutorials/338) assumes that your ATmega32U4 is flashed with a Sparkfun Promicro Bootloader already. If you try to do it with a fresh - out of the box - device you will fail (since Atmel uses a different boot loader).

Hi, ronco
This is a great little DIY board. Did you use the laser printer transfer method to print the board?

Hi,
yes i used the direct toner method ...it works fine for me..
i changed the topic name .. to DIY FC because i dont think thay will be produced..
here are some tips for those who want to build it.
if you just want to build one or two, it may be cheaper to unsolder some sparkfun promicro's because thay have the most of the needed parts on it.
so if you have all parts of a promicro you will just need:
1x MPU-6050
2x 0,1uF
1x 2,2nF
1x10uF
1x10nF
3x 0 Ohm
2x 2k2
i unsolder the promicro on a iron with full power.
you can also solder a ITG3200 or ITG3205 instead of the MPU-6050 .. thay have the same footprint and pin usage.
here is the last version i build. the eagle file is a little different.

felix

Thank you for the additional information. Will add this to the ToDo list with projects:) Need to finish the OSD I'm working on now first and that will test my SMD soldering skills also:)
I'm thinking of adding a second stacked board for the extra sensors if needed.

Congrats! Looking at your layout, I'm just concerned about the fact that you connected the 5V and ground lines from all four ESCs to each other. That may work, but it has high potential to create "
ground loops", which can cause really nasty side effects. I'd suggest to only use the 5V and ground line from one ESC, e.g. the one that is connected to D5 in your layout.

hi,
i cut the + wires of three of my ESC's .. i think its better to have them connected on the pcb for use with servos.. plane mode or bicopter or like.

now there will be a pre prefabricated version of it
.. its a little larger to have mounting holes..
here is a prototype .. the real version will be black.
im work atm on the manual .. the english part will be corrected soon

Nice work! Looking forward to seeing this one in Paul's webshop. So this is like the small brother to
Joerg's microWii board?
The manual looks good, too. At a cursory glance, I spotted two small typos:
- Headline "2.3.3 Spectrum Satellite" (should be "Spektrum")
- In the ESC connection diagram on page 8: "Qaud+" (should be "Quad+")
On page 13, chapter 4.1, the proper term would probably be "LiPo monitoring", not "observation".

i changed it now. and yes it will be the small "simple fly and have fun" brother of joergs "advanced copter control" MicroWii

I like this design !
After square, round and hexagonal boards.
This shape should be nice to see in a frame.
The documentation is also very well done.

Nice job !
Concerning the manual, I also spotted two small typos:
- in the header of the page: "Chose" (should be "Choose")
- In the Power source connection page (4/13): "ATTANTION" (should be "ATTENTION" or "WARNING")

Hello,
first, the NanoWii is a cool project. I got one this week. Currently, there are some Problems with the Setup.
I use Linux (Mint).
When i plug the board into USB, the serial device is ttyACM0. The firmware upload works fine. The
arduino found this device.
But the GUI for setting up doesn't show this device. Has anyone a hint??
regards,
hoppel

Hello,
about the problem with the Serial Interface and the GUI under Linux: it is a Bug in Processing, which is fixed in the next Version. The current solution seems to make a link to /dev/ttyACM0
But i'am not sure, that the board is correctly connected.
What i did: i let the Jumper 1 closed, so that the board is powered via USB only. The green led is on and the red is blinking.
Question: What does the red led indicate??? I dodn't found a description in the pdf file.
If i press at the serial port button in the gui, the red led stops blinking. I press "Stream" nothng happend, i press "Read" nothings is reading.
Yes, i used the dev-Version an uncomment the NanaWii in the code. Is there something else which i had to activate??
Regards,
Hoppel

the red led is the status led and the TX LED .. it should flicker if you have pressed start in the gui.

EDIT:
!!SOLVED!!!
NanoWii + Vista = No driver, it's impossible to install as per the Sparkfun tutorial, I've tried everything.
Does any of you have any ideas?
Thanks

**I manually installed the driver from the .inf file from Sparkfun***

Hello, I had an frustrating Weekend with NanoWii. I tryed so many MINCOMMAND and Minthrottle-Combinations, powered the Board from ESC and tryed from (even seperate) Lipo, first powering FC then ESC'S and the other way round.... always the same: unreproduceable sometimes ESC arm, mostly not.
My setup is 4xsuppo 2212/13, 2xSuppo 25A, 2xSuppo 30A ESC, Frsky ppm, Nanowii.
I tryed the two last 2.1 Releases. (both Releases run perfect on my other Copter with Minniwiiboard) with same setup.
I can upload the code, i can see correct reaktion of sensors and TX in Gui 32bit and wingui.... everything fine; just ESC's are arming only every 100'th try.
yes, ESC's are programmed and calibrated (with software and direkt from Rx manually), yes travel of rx is verifyed in gui from <1000 to>2000.
I've no Idea what else to try.... has Anybody an Idea?

Hi Goetz - MINTHROTTLE should not matter for this - this value just defines the speed at which the motors will spin when the motors are armed (ready to fly). What levels did you calibrate the ESCs for? Did you try setting MINCOMMAND lower than that? I configured mine to go from 1000-2000 and defined MINCOMMAND as 950.
Re: NanoWii atmega32u4 (leonardo) FC
Posted: Tue Jul 17, 2012 4:14 pm

I tryed every 10 Steps from 920 to 1000. Tx is trimmed from 998 to 2011, calibrated Esc's with this ( when not calibrating with MWCode)

Very odd. I'm afraid I have no idea what could be wrong in your case. Does the problem apply to all ESCs equally? I noticed you are using two slightly different models of ESCs.

i noticed that on connect lipo it takes long to init maybe 10 secs.
and the init melody of esc´s is definitly not in sync. quad flies great but i always have strange feeling when esc not beeping in sync dont know why...

Hello mistahead,
have a Look at
http://www.rc-heli-fan.org/quadrocopter ... 92355.htmlThere is an new bootloader, reducing time and (perhaps) getting ESC's in sync...
