Preparing for the SE880 RDK What is Necessary To use the SE880 RDK, you will need: • FTDI USB Drivers • SiRFLive2.0 and above or • A PC with a USB port that fulfills the minimum software requirements: o Windows XP o .NET Framework 2.0  This will be automatically installed by the SiRFLive package if necessary (internet connection is required). 2.1. Installing the USB Drivers Before connecting the SE880 RDK, install the necessary USB drivers. 1 2.2. Double-click the USB driver executable and follow the directions to install the USB drivers. Installing SiRFLive ***NOTE*** SiRFLive does not work on 64-bit OS machine at this time! Minimum PC requirements: • Pentium CPU 2 GHz • 1 GB of RAM • 100 MB hard drive Recommended • 2 GB of RAM • 1280 x 1024 screen resolution Ensure that all previous installation versions of SiRFLive have been uninstalled before installing any newer versions! Install the current SiRFLive with the attached installer. Follow the installer directions until finished. Users should allow SiRFLive to install to the default location – C:\Program Files\SiRF\SiRFLive, but it can be changed if necessary.

SE880 RDK Reference Layout The reference schematic and PCB layout are provided in the USB memory which comes alone with the RDK. The performance of SE880 will be optimized with the following guidelines: 1. Use the bottom layer (layer-2) as the big ground plane for both RF and heat transfer. 2. The ground plane with via holes under the SE880 (shown in Figure 3) serves two purposes: a. Provide a good RF ground plane for the SE880. b. The big via hole dominates heat transfer from the SE880 to the big ground on layer-2. This enhances TCXO implementation by provide the TCXO a thermally stable environment. Heat transfer of copper is 1400 times fast than FR4. 3. Coplanar waveguide calculator should be used to determine the appropriate transmission line structure to achive 50 Ohm input trace for the antenna at 1.575GHz.. Good thermal transfer and RF grounding 2-layer FR4, 1.6mm thickness, 2oz copper Figure 3: SE880 PCB Layout Reproduction forbidden without written authorization from Telit Communications S.p.A. - All Rights Reserved.

Before connecting the RDK, ensure that the USB drivers have been installed. 2. As soon as the evaluation board is connected to the PC, it will be detected and installed. Figure 4: USB installation, select “Continue Anyway” to proceed. 3. After the evaluation board has been installed, check the “Device Manager” window for the evaluation board COM port number. This information is needed for use with the GPS tools.
