Introduction to the Evaluation Kit

Note the following:

The expansion board is an Arduino-compatible shield attached to the Arduino-
compatible header.

The JN5168-based module which is pre-fitted to the module site has been pre-
loaded with the JenNet-IP Smart Home demonstration.

An antenna aperture can accommodate one of the supplied push-through
antennas and is for use with a module that uses a uFL antenna connection (see
Section 1.3.4 ).

If the board is powered using the 12V DC power supply unit provided in the
evaluation kit, it is possible to power two or more boards from this one power
supply by daisy-chaining them together using the supplied cable.

In low-power mode, which uses just 2 AAA batteries, only the JN516x module
is powered (this mode can be used to make low-current measurements).

The board is supplied with the SPI jumper in the SSZ position in order to enable
access to the on-board Flash memory device for applications that need it

To return to the factory settings (including for the fitted module), wait at least 2
seconds following power-up, then press the Reset (RST) button on the Carrier
Board 4 times with less than 2 seconds between two consecutive presses.
