PRELIMINARY INFORMATION
Jetson Orin NX Series and Jetson Orin Nano Series DG-10931-001_v1.1 | 11
Chapter 4. Developer Kit Feature
Considerations
The Jetson Orin Nano Developer Kit carrier board design files are provided as a reference
design. Both Jetson Orin Nano and Jetson Orin NX modules are compatible with this carrier
board. This chapter describes details necessary for designers to know to replicate certain
features implemented on the NVIDIA Jetson Orin Nano Developer Kit carrier board 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-GR)
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. It is
recommended that the connections used on the reference design are followed exactly to be
compatible with the firmware provided to ensure correct functionality.
