Those adapters have the problem that you can't get decoupling capacitors
close to the chip, and the power distribution won't be very good.

Interesting discussion. If I may ask you a couple of questions:
- what are you really trying to do? I don't mean "read sensors", I
mean what is the application ?
- what is being sensed, where, how often, what happens to the data?
- where are you? Private hobbyist, school, college, university,
company.
Answers to the above would help the audience on this list provide
answers with the right context.
Thanks,

Hello,
> - what are you really trying to do? I don't mean "read sensors", I
mean what is the application ?
>- what is being sensed, where, how often, what happens to the data?
I'd like to write an application which read values from some sensors
like temperature, humidity, motion detector and
displays it on a LCD display. I'd like to read values each seconds and
to update each time the values.
I need to send these values via bluetooth so I've bought a wt11 module
from Bluegiga and I need to connect it to the ARM, too.
So the main application is to read the values and to send them via
Bluetooth.
I'm doing this very well on Arduino duemilanove, but now I'd like to
switch to the ARM because I want to develop a system all by myself;
in this way i'll learn a lot of things.
I've bought two ARM devices and this is their datasheet:
http://docs-europe.origin.electrocomponents.com/webdocs/0db0/0900766b80db0f69.pdf
and this is the photo of one of them:
http://lnx.mangaitalia.net/IMG_2313.jpg
>- where are you? Private hobbyist, school, college, university,
company.
I'm in Italy and I'm a mechatronic engineer but I have no skill on
these devices so I'd like to receive some advices from you.
I'm doing this as a personal project and I don't have to do this for
business or for a company.
I just have to improve my skills.
I hope you can help me and suggest me the best way to realize my
project.

Here are a couple of STM32F prototype boards:
http://www.sparkfun.com/search/results?term=stm32f&what=products
A couple of years ago I needed a system that would accept data over SPI from an FPGA. The system would then reformat the data substantially and send it to a networked HP LaserPrinter.
Not conceptually difficult but building the PCB would be more than I wanted to go through. I wanted the result, not the effort.
So, I built a 'motherboard' that handled the power supplies and interconnects. I just soldered in two 'daughterboards' like these:
http://www.sparkfun.com/products/263
http://www.sparkfun.com/products/200
I did almost NO board design, just a few interconnects, and then soldered the purchased boards in place. Simple!
The difficulties in creating a one-off board are many. I would, at least, start with a proven electrical design like those on the STM32F boards above. The schematics are available.
I would probably BUY one of the boards whether I used it or not just to see how they handled the physical layout of bypass capacitors, the crystal(s) and power supply. These things can jump up and bite you! It just isn't that simple to design a board.
Besides, most hobbyists are limited to two sided boards if for no other reason than cost. It isn't easy to get all the power and ground paths routed and still have room for signals.
The suggestion earler that you have 0 chance of success may be a little harsh but it is VERY difficult to have the first version work. Or the second... Or the third... It is far better to use prototype boards and get a system working before trying to design a board.

Hi Rocco,
Thanks for putting the project into context. I think I understand what you're
up to now. If you don't mind, I have few more quick questions:
First, is one of the skills you're trying to pick up the ability to design a
circuit board? If so, do you have a particular CAD package already that you
want to use to capture the schematic and lay out the circuit board?
In general terms, how much money are you prepared to spend on this exercise? Is
a few hundred euros a major outlay or a minor expense?
Best regards,
Norman

Rocco,
It is very easy to solder, use a lot of flux and a good iron, for
desoldering you will need a hot air blower.
I've solded all this SMD board with the mentioned material only.
http://picasaweb.google.com/lh/photo/80t50BujNde_Qvx-iCWeRUT896nRqSOBm3Lop2ZwKHo?feat=directlink
Watch some videos on youtube about SMD soldering, its not hard at all,
unlike BGAs.

A little birdie told us:
"I've never soldering a smd device,"
Please do your self a favor and just get some hardware.
All you postings are about your application.
And when you do not have hardware to run, what will happen to your application ?
But, if you heart is set on building your own hardware, please get a photo site and let us see how you are doing.
Please show us the working application with "sensors" and "lcd" display running.

A little birdie told us:
"I've never soldering a smd device,"
Please do your self a favor and just get some hardware.
All you postings are about your application.
And when you do not have hardware to run, what will happen to your application ?
But, if you heart is set on building your own hardware, please get a photo site and let us see how you are doing.
Please show us the working application with "sensors" and "lcd" display running.

Thanks for putting this project into context.
Rocco said " I got a free sample of the chip and I do not have the money to do it right. So help me do it at all and I will blame all of you if it does not work."
Yes, I understand Rocco now.
Good luck
