+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
