Nvidia Jetson Orin NX User Manual

PRELIMINARY INFORMATION
NVIDIA Jetson Orin NX DG-10931-001_v0.1 | 9
Chapter 4. Developer Kit Feature
Considerations
The Jetson Orin NX module is compatible with the NVIDIA Jetson Xavier NX Developer Kit. The
Jetson Xavier NX Developer Kit carrier board design files are provided as a reference design.
Not all the Jetson Orin NX features can be used on the Jetson Xavier NX Developer Kit. In
addition, there are some features on the developer kit that are not supported when used with
the Jetson Orin NX module. This chapter describes details necessary for designers to know to
replicate certain features if desired. In addition, aspects of the design that are specific to the
NVIDIA developer kit usage but not useful or supported on a custom carrier board are also
identified.
Most of the features implemented on the reference design can be duplicated by copying the
connections from the reference design. Some of the following features have aspects that
would require additional information.
 Button Power MCU (EFM8SB10F2G)
 USB SuperSpeed Hub (Realtek RTS5420)
 Power over Ethernet (PoE)
 TI TXB0108 level shifters
 ID EEPROM (Not to be copied from reference design)
4.1 Button Power MCU
The reference design implements a button power MCU (EFM8SB10F2G). This device is
programmed with firmware that is available on the Jetson Download Center. The posting is
titled
Jetson AGX Xavier and Jetson Xavier NX Power Button Supervisor Firmware . The
connections used on the reference design must be followed exactly and the firmware provided
must be used to ensure correct functionality.
