Migration between SARA modules
A.1 Overview
The SARA-G3 2G modules, the SARA-U2 3G / 2G modules, the SARA-R4 LTE Cat M1/NB1 / 2G modules
and the SARA-N2 LTE Cat NB1 modules have exactly the same u-blox SARA form factor
(26.0 x 16.0 mm, 96-pin LGA), with compatible pin assignment as described in
Figure 35 , so that the
modules can be alternatively mounted on a single application board using exactly the same copper
mask, solder mask and paste mask.

SARA modules are also form-factor compatible with the u-blox LISA, LARA and TOBY cellular module
families: although each has a different form factor, the footprints for the TOBY, LISA, SARA and LARA
modules have been developed to ensure layout compatibility.
With the u-blox “nested design” solution, any TOBY, LISA, SARA or LARA module can be alternatively
mounted on the same space of a single “nested” application board as described in
Figure 36 .
Guidelines in order to implement a nested application board, description of the u-blox reference
nested design and comparison between TOBY, LISA, SARA and LARA modules are provided in the
Nested Design Application Note
[7] .
