+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.
+
+- 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
+ case)
