All,

I want to do some prototyping with Locosys UC-1513 GPS modules.

I have the modules and I need someone to make some breakout boards for me (I'll supply the modules).

I don't want anything fancy, just convert them to a 22 pin DIP on a 2.54mm spacing so they plug straight into a Breadboard including header pins.

At the moment I think I want 4 fully manufactured boards and two spare blanks

Does anyone have any suggestions on who can do this. I really want someone in Australia as I will need to post the modules to them.

Thanks
Chris

PS Here is a link to the datasheet http://www.locosystech.com/product.php?zln=en&id=38

I can do it but I hope you realise the horrendous set up cost for just a few PCBs. :)

Maybe it is just me, but I couldn't find much info on the web site...

Where is the real data sheet?

Is your module to include an LNA or just use the one built-in?

Is your module to include a dc power connection for the antenna, coupled on the RF?

Is your module to include a chip antenna, patch antenna, antenna connector?

Will your module include RS-232 or USB?

How about a 1 pps LED, Signal Lock LED, etc.?

Even if the description of what you desire specified this in more detail, the web site is still useless at providing the info needed to undertake the project.

Hi JC,

Its a straight 22 pins extended out to 2 x 11 pin headers. Thats it. No other electronics at all. The ultimate design is intended to be as compact as possible but that is an entirely different story. Generally, I am interested in the creative/design part of the development, building PCB's and precision soldering is a skill I would have to learn and still be really inefficient at. Best left to the experts I say.

As far as RS232 or USB - USB as it is a handy way to charge batteries and pretty much the default standard now

Jackons (if I remember the name correctly) have some really neat ultra small chip antenna that I'll be using and it'll be using the built in LNA.

The real data sheet is a PDF at the bottom of the page - this has the pin layout.

Hi John - How horrendous?

Chris,

Bread boarding a GPS antenna signal is apt to be a problem. That is why I raised the questions above. Typically one would mount at least the GPS antenna on the breakout board adjacient to the GPS module, or run the trace to a RF connector via a short coax.

It doesn't mean you can't give it a try!

Have you looked at some of Spark Fun Electronics GPS modules to see how they have done some of their breakout boards? SFE GPS's .

JC

PS: I am not trying to steal John's business, just throwing out a few thoughts.

For a start, a pcb run is going to cost around $400, then the cost of designing the pcb. Whilst it may be simple, you're going to burn a couple of hours to read and understand the datasheet, draw a schematic and pad layout for the device then lay out the pcb and check it. Then the labour of ordering the pcbs, then populating them. So we're talking a few hours in labour alone. So, at commercial rates, we're talking about $1000.

Thanks Guys

JC, yes, I must admit I did consider putting the Antenna on the board as I have a few of the mini ceramic antennas at hand as well (Same as the SFE ones http://www.sparkfun.com/commerce/product_info.php?products_id=9131 ). I've been sitting on this project for so long and the main hold up is hooking up the module. I thought if I could at least get it expanded out to a DIP I could get leg on with it.

And yes you are right they are a non standard layout (I've researched this extensively) so you have to start from a pad layout. I've done this in both Eagle and Kicad but really haven't got much further.

I'd be happy if even someone designed the board for me and I coudl send it off to Sparkfuns BatchPCB or Futurlec to make it and then I might have a crack at using a skillet to reflow.
