EVK-L2x overview
The EVK-L20 and EVK-L21 are powerful and easy-to-use tools that simplify the evaluation of u-blox TOBY-L200
and TOBY-L210 LTE/DC-HSPA+/EGPRS cellular modules.
The evaluation kits differ depending on which TOBY-L2 series module version is mounted:
TOBY-L200 module is provided on the EVK-L20 evaluation kit
TOBY-L210 module is provided on the EVK-L21 evaluation kit
This document identifies both evaluation kits as EVK-L2x.
This section describes the main connections and settings required to get started.
