Table 39: Summary of SARA-G3, SARA-U2, SARA-R4/N4 and SARA-N2 modules interfaces
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 60. Guidelines
for implementing a nested application board, a description of the u-blox reference nested design and a
comparison between the TOBY, LISA, SARA and LARA modules are provided in the Nested Design
Application Note [21].
