m-pad-hardware — M-Pad hardware development

[M-pad-hardware] Hello from SVHMPC

[Tom C. <tom...@go...>]

Hello!

I came across your project after reading a post on the GNU radio
mailing list. The project looks very interesting. I work with the
Silicon Valley Homebrew Mobile Phone Club (SVHMPC). If you've not
heard of us, we're a group of people trying to create our own
"homebrew" mobile phones. Most people use Gumstix devices at the heart
of their phones, however there are a few of us who are looking at the
"next-gen" devices. I personally have a Freescale i.MX31 development
board I'm using to try out bits of software.

Our wiki has got a fair bit of content on it now and is available at
http://hbmobile.org/wiki/index.php?title=Main_Page. We also have a
mailing list you can sign up to at
http://telefono.revejo.org/mailman/listinfo/svhmpc_telefono.revejo.org


Your project is interesting to us because you aren't using a Gumstix
and you seem to want to add a 2700 graphics processor, which the
Gumstix doesn't have. This is actually why I'm working with the
i.MX31, as it has an integrated PowerVR MBX core (the same as the
2700). I have a few questions if you'll indulge me...

1) Are you aware of the Gumstix modules, if so, what was your rational
for using the Colibri boards rather than the Gumstix boards?
2) Looking over your schematics, you seem to be making a carrier board
which the Colibri PXA270 module plugs into. Is this correct? Are all
your peripherals going onto the same board or are you going to split
them off onto separate boards?
3) How far into the project are you? You seem to have schematics
available, do you have any hardware yet?
4) How are you intending to add the 2700G processor? Also, what are
you doing about the drivers for the 2700? I've tried in the past to
get a copy of the MBX Linux DDK and failed. Have you signed a NDA with
Imagination Technologies?

Your project seems so similar to what people at the SVHMPC are doing,
surely there is some collaboration to be had?

Cheers,

Tom

Forgot to mention the flex-print wifi and cellular antennas, this is probably the best way to
put antennas in a mobile device.

cheers,

After reading some page, I think I have to change my suggestion.

SiRF II is an old chip and I think they discontinue to produce such =
chip.
The SirF III is the modern version. Also the EM-402 has no connector. =
The module has to be solder directly on the PCB.

I think we have to choose between EM-406a (RoHS) or the EM-411.

Both are more or then less the same modules with the same =
specifications.
Both using 4.5V to 6.5V and a 6pin connector. The EM-411 has a 1PPS =
output instead of the NC from EM-406.

That means with an 0-Ohm resistor and a special cable we can design the =
schematics in a way that we can use=20
different GPS modules like the EM-408 or even the EM-401.

Okay that means also we delete the 3.8V power switcher in the =
PowerTestBoard and in the M-Pad-Mini Schematics.


Any comments?

Cheers

Re: [M-pad-hardware] new tiny GPS module

[<jue...@cr...>]

Okay good to know.

I have made a comparision between various GPS modules.
>From my point of view is size, power consumption and availablity the =
main reasons to buy one.

Here is my table

Name      =A6 Size in mm    =A6 Power in mW =A6 Cost =A6 Sens. in dBm =
=A6 Comments
-------------------------------------------------------------------------=
--------------------
EB-85A    =A6 30x30x8.6     =A6 108.9~195mW =A6 100$ =A6 -158dBm      =
=A6 Small size, but high costs
EM-401    =A6 41x41x14      =A6 89~264mW    =A6 72$  =A6 -170dBm      =
=A6 High sensetivity, high prize and big size=20
EM-402    =A6 28x30x5       =A6 264mW       =A6 66$  =A6 -175dBm      =
=A6 Good size and sens., middle prize, high power
EM-406    =A6 30x30x10.5    =A6 350mW       =A6 56$  =A6 -159dBm      =
=A6 Good size, low prize, high power
EM-408    =A6 36.4x35.4x8.3 =A6 247.5mW     =A6 60$  =A6 -159dBm      =
=A6 low prize, high power
Lassen-IQ =A6 26x26x6       =A6 89mW        =A6 50$  =A6 -130dBm      =
=A6 No built in antenna, low power and low prize


When I check out the table above, I would choose EM-402 due to the small =
form factor.
The only negativ point is the high power consumption but I think that =
the EM-402 has also a power save funnction like the EM-401
Plus it has also a second connector for an external antenna.


Any comments, suggestions, ideas?

Re: [M-pad-hardware] new tiny GPS module

[<jue...@cr...>]

This tiny module isn't that tiny.

I have drawn a schematics with that module.
You need a lot of condensators, one cristal and some resistors.
And of course an antenna.

At the end you are on the same size like the Lassen IQ.

So I'm not quite sure if should take the MN1010 or the Lassen IQ.

I tend more for the Lassen IQ because of the following reasons:

-- Good EMC
-- You can buy special embedded active antennas.
-- You only need 3.3V not 1.8V

For the M-Pad project, I think we should only implement the Lassen IQ =
and drop the GSM862 due to space problems.
When we drop the GSM module then we can also save a voltage switcher for =
the 3.8V.

Any comments, ideas about that topic?

Cheers

I have downloaded the datasheets and I will add the device to the =

Jamie, I started to make a power test board.
It includes all power switcher, battery charger, ATMEGA406 and the =

ATMEGA406.

If you like you can start with the layout when you received my =

I think the board shouldn't be very expansive when we design it only for =

One goal of this part project should be to make a power board on a very =

What do you think about it?

Tell me your ideas, concerns.

[M-pad-hardware] new tiny GPS module

[Jamie M. <jm...@sh...>]

Hi guys, 

A 10mm x 10mm 12channel GPS module:

http://www.sparkfun.com/commerce/product_info.php?products_id=8291

[M-pad-hardware] multi touch screens

[Jamie M. <jm...@sh...>]

Hi guys,

Some interesting links on multi touch screens:

"http://www.hindu.com/thehindu/holnus/008200701180944.htm"

"http://en.wikipedia.org/wiki/Multi-touch"

"http://www.fingerworks.com/"

"http://cs.nyu.edu/~jhan/ftirtouch/"

They use optical sensing to detect multiple
simultaneous touches on the screen.  I'm not
sure if the optical sensor is behind the LCD or
not?

cheers,
Jamie

They looking great. But I think we have to finish first the motherboard.
After finishing the mainboard we can start making our own module with =
the blackfin chip.

Or we make a complete new different board.

What do you think.

Hi,

Here is a single chip AM/FM tuner IC:

Re: [M-pad-hardware] barometric pressure sensor

[<jue...@cr...>]

Hi Jamie,

It is a nice device.
I have added it to the new library. I also added the accelerometer =
SCA3000.
I tried to released a new version of the library last week but it was =
rejected by cadsoft.
Now I will release the new license today.

I hope you will like it. It contains tons of new devicese.=20

I will also release a new version of the single sheet schematics.

Have you seen on toradex. They have released some colibri modules with =
the PXA290.
They also told me that the datasheet of the pxa290 will be released =
soon.

As you mention it  weeks before the PXA290 is an integrated graphic =
accelerator like the one in Intel's 2700G.
That would mean we don't need to use the 2700G.

I will try to get some more infos from Toradex.

Best regards

Juergen

Hi everybody

I have asked Toradex about the powerconsumption of there sodimm modul =

This is quite good for a module with some many different devices on it.
