Appendix
A Migration between SARA modules
A.1 Overview
SARA-G3 2G modules, SARA-U2 3G / 2G modules, SARA-R4/N4 LTE Cat M1/NB1 / 2G modules and SARA-
N2 LTE Cat NB1 modules have exactly the same u-blox SARA form factor (26.0 x 16.0 mm, LGA 96-pin),
with compatible pin assignments, as in Figure 59. Any one of the modules can be mounted on a single
application board using exactly the same copper mask, solder mask and paste mask.
