We are looking for engineering assistance developing a ARM SoC PCB for a commercial product. Ideal candidate will be US based, Chicago area a big plus. Demonstrated experience in pcb design with ARM SoC's, with some references of past work. Company Engineer who is looking to make some side money, or graduate EE student perhaps. /// Rough requirements are (more details will be provided after NDA:) ARM SoC @200mhz - @400mhz Board to run Linux (with CE support also a plus) On Board GPS + Antenna (Trimble or Sirf or ?) ARM connected to GPS via serial/UART. AC97 audio, line in for microphones(s) Mono Audio amplifier @ 500mW Circuiry for LiIon charging / power managment 16mb Ram 16-32mb Flash /// Due to product design, we need to keep this as compact as possible. Ideal board size would be 120mm*40mm*7mm (with LiIon battery located elsewhere) We may also want to investigate two (or three ?) boards connected with a flex ribbon. We need production ready designs, gerber/orcad or eqiv pcb layout. Designs must me free of IP rights and Royalty free. We will handle manufacturing. We will pay a good industry standard rate for this, timeline is PCB prototype development by April 06 or sooner. Contact armpcbdesign@yahoo.com if you can do this.

I will suggest that for a commercial product you are likely to get a much better result if you get an experienced independent designer or design house to help you. It will cost more than someone moonlighting or just out of college but you stand a chance of getting a decent job. Michael Kellett www.mkesc.co.uk

You can do better signal-to-noise filterings than the Sirf, as well as different frequency channels. With the EC and US releasing competiting GPS resolutions, you don't want to tie to the old resolution based modules.> ... > Due to product design, we need to keep this as compact as possible. > Ideal board size would be 120mm*40mm*7mm (with LiIon battery located > elsewhere) > We may also want to investigate two (or three ?) boards connected with > a flex ribbon.At least two boards, with the RFs on a separate board, probably single-sided with solid plane on the other side.> ...> Contact armpcbdesign@yahoo.com if you can do this.If you are doing it for the US army, they will probably ask for the upgrading resolutions on both standards. Just in case they have to put solders in Europe. Oh, sorry, they already have.

They implement the full GPS function and communicate over a serial port. Some also provide software support so you can add your own code to the ARM CPU which is on most of them.

The RF chip is about $20 + another $20 for a DSP. Of course, you have to do some programmings.

Basically the module is a vehicle for selling the chips. In fact, the module approach saves you having to develop all the firmware since it is included in the on-module ARM. They are selling these modules for the cell phone market, so I can't imagine that it has much overhead cost or the cell phone makers would just use the chips.

We would not be buying 10k. One quote I got was: Sample pricing is US$210.00 per unit 100 units for production = US$180.00 per unit 500 units for production = US$165.00 per unit The RF chip could be less than $10 if you are buying 10K.

To the best of my knowledge everyone still has a three chip solution. I guess there may be some who have combined the baseband processing with an ARM chip as a custom SOC solution, but I have not seen that yet. Who did you get your quotes from? Check with uBlox or Fastrax. They seem to have the best modules at this point, at least in terms of size, power and cost. Pricing at 100 is $46 and at 500 is $34. uBlox has new modules that are indoor capable with 157dBm sensitivity rating. The price is only a bit more. If you need contacts, I can send you mine.
