I'm using a module at the moment. In the future it might be profitable to look at the Atmel arm chip with the built in GPS receiver (and 2D graphics accelerator) but for now it's a module. MN1010 will pull up some info on the current module, but that can change at any time. -Adam On 6/7/07, Vasile Surducan wrote: > Don't be affraid, we know.
