EVK-U2x overview
The EVK-U26 and EVK-U27 are powerful and easy-to-use tools that make evaluating the u-blox SARA-U260 and
SARA-U270 HSPA/UMTS/EGPRS/GSM cellular modules simple.
The evaluation kits differ depending on which SARA-U2 series module version is mounted:
SARA-U260 module is provided on the EVK-U26 evaluation kit
SARA-U270 module is provided on the EVK-U27 evaluation kit
This document identifies both evaluation kits as EVK-U2x.
This section describes the main connections and settings required to get started.
EVK-U2x can also be used to evaluate other SARA-U2 series modules as SARA-U280.
See the
SARA-U2 series Data Sheet
[2] and
SARA-G3 / SARA-U2 series System Integration Manual
[3] for
the features supported by u-blox SARA-U2 series HSPA/UMTS/EGPRS/GSM cellular modules.
