Chapter 3. Developer Kit Feature
Considerations
The Jetson TX2 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.
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 Jetson Xavier NX Developer Kit carrier board design
can be duplicated by copying the connections from the P3509 carrier board 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 recommended to be copied from reference design)
3.1 Button Power MCU
The developer kit carrier board 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.
