8. Mechanical Application Notes
1. CON0 and CON1 are IPEX1 connectors on top side
2. P1 is 2*10 pins 1.27mm male header on bottom side for signals
3. 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.

5. H1, H2, H3, H4 are slot holes used for install metal shielding cover if needed
6. D1 is diameter 2.1mm hole for screw fixing
7. D2 is diameter 2.1mm half hole for screw fixing
8. 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.
