The SARA modules are also form-factor compatible with the u-blox LARA, LISA and TOBY cellular
module families: although each has a different form factor, the footprints for the TOBY, LISA, LARA
and SARA modules have been developed to ensure layout compatibility.
With the u-blox “nested design” solution, any TOBY, LISA, LARA or SARA module can be alternatively
mounted on the same space of a single “nested” application board as described in Figure 76.
Guidelines to implement a nested application board, description of the u-blox reference nested design
and comparison between TOBY, LISA, LARA and SARA modules are provided in the nested design
application note [17].
