2. OVERVIEW
Telit IoT Development Kit (EVK4) is a system that permits to test Telit module development
possibilities using the Module’s embedded Appzone environment in connection with the
hardware this board is offering.
The board is provided with external sensors (i.e. Temperature / Gyroscope / Light) that can
be controlled through an I2C bus to collect measurements that can then be elaborated with
an user defined script.
The information presented in this document is believed to be accurate and reliable.
However, no responsibility is assumed by Telit Communications S.p.A. for its use, nor any
infringement of patents or other rights of third parties which may result from its use. No
license is granted by implication or otherwise under any patent rights of Telit
Communications S.p.A. other than for circuitry embodied in Telit products. This document
is subject to change without notice.
