[J14]: 12-pin button header. Brings out system power, reset, force recovery, UART
•
console, and other signals:
Pin 1 connects to LED cathode to indicate System Sleep/Wake (Off when system
•
is in sleep mode).
Pin 2 connects to LED anode.
•
Pins 3 and 4 are respectively UART Receive and Send.
•
Pins 5 and 6 disable auto power-on if connected.
•
• Pins 7 and 8 reset the system if connected when the system is running.
Pins 9 and 10 put the developer kit into Force Recovery Mode if they are
•
connected when it is powered on.
Pins 11 and 12 initiate power-on when connected if auto power-on is disabled.
•
[J15] RJ45 connector for gigabit Ethernet. The connector includes two lights: an
•
amber light to indicate activity, and a green light to indicate link speed. The green
light is on for a 1000 Mbps link, and off for a 100 Mbps or 10 Mbps link.
[J16] Power jack for nominal 19-volt power supply. (The maximum supported
•
continuous current is 4.4A.) Accepts a 2.5×5.5×9.5 mm (ID × OD × length) plug with
center positive polarity.

Power Guide

The Jetson Xavier NX Developer Kit requires a 9−20V power supply. The 19-volt power
supply packaged in the kit attaches to power jack [J16].
The Jetson Xavier NX module is designed to optimize power efficiency and supports
two software-defined power modes. The default mode provides a 10W power budget
for the module; the other provides a 15W budget. These power modes constrain the
module to near their 10W or 15W budgets by capping the GPU and CPU frequencies
and the number of online CPU cores at a pre-qualified level. See
Developer Guide for details about power modes.
