Module Power
The JN517x module site can be supplied with a voltage of 5V or 12V, which is
controlled by the Switches Module Power Supply (SMPS) and configured using the
jumpers
JP4-1
and
JP4-2
:
5V supply:
Both
JP4
jumpers must be in the factory-default
LOW
position.
This setting is used when the power supply to the Carrier Board is regulated 5V
from an external DC/USB source or unregulated 5V from batteries.
12V supply:
Both
JP4
jumpers must be in the
SMPS
position. This setting
must be used when the power supply to the Carrier Board is 12V from an
external DC source.
The above jumper settings are illustrated in
.
Caution: When using an external DC Power Supply
Unit (PSU) with a Carrier Board, only a 7-12V PSU with
a 2.1-mm connector must be used.
Figure 17: JP4 Jumper Positions
Caution: The JN5179 modules supplied in the
development kit require a 5V supply. Using a 12V supply
will damage them. The 12V option on the Carrier Board
is provided for future use.
