Appendix
A Migration between TOBY-L1 and TOBY-L2
A.1 Overview
The 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.

TOBY modules are also form-factor compatible with the u-blox LISA, SARA and LARA cellular module
families: although TOBY modules, LISA modules (33.2 x 22.4 mm, 76-pin LCC), SARA modules (26.0 x
16.0 mm, 96-pin LGA) and LARA modules (26.0 x 24.0 mm, 100-pin LGA) each have different form
factors, 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 83 .
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
[28] .
