Memory configuration Depending on customer's request, the module can be shipped with following configuration : Flash size : 2MB, 4MB, 8MB, 16MB, 32MB, 64MB DDR2 size : 64MB, 128MB 8. Mechanical Application Notes 1. 2. 3. CON0 and CON1 are IPEX1 connectors on top side P1 is 2*10 pins 1.27mm male header on bottom side for signals P2 is 2*14 pins 1.27mm male header on bottom side for signals 4. Footprint of P1, P2 is as following, the coordinate of pin1 footprint center for P1 and P2 are (29.5, 10.975) and (9.575,1.425), Please note that this coordinate is the center of pad, not center of header pin.

H1, H2, H3, H4 are slot holes used for install metal shielding cover if needed D1 is diameter 2.1mm hole for screw fixing 7. 8. D2 is diameter 2.1mm half hole for screw fixing P3 is a 2 pins dip type header holes with 1.27mm pitch. Since P1 and P2 are all located on lower side, this socket can be used optionally to mount module on base PCB for balancing the force of upper side. 9. The mechanical drawing in .dxf format is available under request. 9.Compliance FCC Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference and(2) this device must accept any interference received, including interference that may cause undesired operation.
