+nPM1100 EK
+##########
+
+Overview
+********
+
+The nPM1100 EK lets you test different functions and features of the nPM1100
+Power Management Integrated Circuit (PMIC).

+
+Requirements
+************
+
+The nPM1100 EK board is not designed to fit straight into an Arduino connector.
+However, the Zephyr shield is designed expecting it to be connected to the
+Arduino shield pins. This allows to use the shield with any host board that
+supports the Arduino connector. The connections are:
+
++-----------+--------------+
+| PMIC Pin  | Arduino Pin  |
++===========+==============+
+| ISET      | D2           |
+| MODE      | D3           |
++-----------+--------------+
+
+Usage
+*****
+
+The shield can be used in any application by setting ``SHIELD`` to
+``npm1100_ek``.
