B Migration between TOBY-L1 and TOBY-L2
B.1 Overview
TOBY-L1 and TOBY-L2 series cellular modules have exactly the same TOBY form factor (35.6 x 24.8 mm LGA)
with exactly the same 152-pin layout as described in Figure 82, so that the modules can be alternatively
mounted on a single application board using exactly the same copper mask, solder mask and paste mask.

Figure 82: TOBY-L1 and TOBY-L2 series modules pad layout and pin assignment
TOBY modules are also form-factor compatible with the u-blox LISA and SARA cellular module families: although
TOBY modules, LISA modules (33.2 x 22.4 mm, 76-pin LCC) and SARA modules (26.0 x 16.0 mm, 96-pin LGA)
each have different form factors, the footprints for the TOBY, LISA and SARA modules have been developed to
ensure layout compatibility.
With the u-blox “nested design” solution, any TOBY, LISA or SARA module can be alternatively mounted on the
same space of a single “nested” application board as described in Figure 83. Guidelines in order to implement a
nested application board, description of the u-blox reference design as nested application board and comparison
between TOBY, LISA and SARA modules are provided in the
Nested Design Application Note [32].
