+Footprint length is from the tip of the sleeve to the rearmost pad
+edge or to the rearmost part of the case, whichever if further away.
+
+
Critical dimensions:
- footprint width: in the original GTA02 design, the space available
between the shields on both sides of JK4401 is only about 8.2 mm.
+ The distance between the pad edges that are closest to the shields
+ in GTA02 is 7.2 mm.
+
+ If we assume the same center but no GSM shield, the distance from
+ the center to the edge of the pads of the main shield would be
+ 4.7 mm.
+
+- footprint length: in the original GTA02 design, the distance from
+ the tip of the sleeve to the battery connector is about 16.4 mm.
+
+ The distance from the tip of the sleeve to the edge of the outmost
+ pad of the battery connector (only for support, without electrical
+ connection) is 13.5 mm.
+
+ The distance from the tip of the sleeve to the edge of the outmost
+ connecting pad of the battery connector is 16.8 mm.
+
- outer diameter of sleeve: the sleeve fits into a hole in the case
and it helps to keep the PCB in place (similar what USB connector
and external GPS antenna connector do on the opposite side of the
