Visit Sparfun.com for ideas and other modules that can be combined with the GPS modules.

Do you have any USB boards for these?

Elifromthevi · 03-04-2009, 01:23 PM

I do not have any but www.sparkfun.com or also http://www.ftdichip.com/FTProducts.htm which they sell most of their modules on digikey.com website.

Serial is better interface than usb because with a usb adapter all its doing is creating a USB interface converting the SERIAL data back to SERIAL data on a virtual COM port.

Great seller! I got my item in today. Happy that its got the "MMCX to SMA" cable. However, I'm a bit confused, can I just plug this straight into my motherboard's COM port header? The motherboard has a 2 row header. Or is there a nice adapter I could just buy?

Best option is to splice the mate to your MB COM port connector into the cable provided. should be GND, TX, RX, and VCC ((3.3 or 5V) two wires i believe one is enable other is PWR). Compare pinout against the Data sheet of the EM408 GPS on last page pay attention to the view of the connector and the wires in each socket.

is this cable suitable for EM-408? http://www.ftdichip.com/Products/Eva.../USB-RS232.htm

If so is there any other components I need like voltage converter etc?
