Hi,
I am designing the carrier board for NVIDIA Jetson Orin AGX 64GB. Here the input is only 12V DC (not through any other sources like USB or PoE). I am referring the “Jetson Orin Developer Kit Carrier Board design (base version)” for my new carrier board design.
Please guide me which Section I can completely ignore only for Power design in case the input power is only 12V DC.

When designing a carrier board for the NVIDIA Jetson Orin AGX 64GB with a 12V DC input, you can refer to the Jetson Orin Developer Kit Carrier Board design as a base. Since your input power is only 12V DC and not through other sources like USB or PoE, you can ignore certain sections related to those power sources. Here’s a breakdown of what you can ignore and what you should focus on for the power design:
Ignore:
USB Power Section: Since you’re not using USB as a power source, you can ignore the sections related to USB power delivery, such as USB voltage regulation, USB power switching, and USB power monitoring.
PoE (Power over Ethernet) Section: As you’re not using PoE, you can ignore the sections related to PoE power delivery, PoE voltage regulation, and PoE power monitoring.
Battery Charging and Power Management: If your design doesn’t include a battery or battery charging circuitry, you can ignore the sections related to battery charging, battery monitoring, and power management for battery-powered systems.
Power Sequencing for Multiple Power Sources: Since you’re only using a single 12V DC input, you can simplify the power sequencing and ignore the sections related to power sequencing for multiple power sources (e.g., USB, PoE, and DC).
Focus on:
DC Input and Filtering: Ensure that your design includes proper filtering and protection for the 12V DC input, such as EMI filtering, surge protection, and voltage regulation.
Power Supply (Component): Focus on designing a reliable power supply for the Jetson Orin AGX 64GB module, which includes the power sequencer, voltage regulators, and power monitoring.
SYS_RESET* (Component): Understand the SYS_RESET* signal, which is used to reset the system. Ensure that your design properly handles the SYS_RESET* signal, including the power-on reset and power-off reset.
POWER_EN (Component): Implement the POWER_EN signal, which controls the system power state. This signal is used to enable or disable power to the module.
Voltage Regulation and Power Distribution: Design a robust voltage regulation and power distribution system to ensure that the Jetson Orin AGX 64GB module receives the required voltages (e.g., 3.3V, 5V, and 1.8V) and currents.
Power Monitoring and Protection: Implement power monitoring and protection mechanisms, such as overcurrent protection, overvoltage protection, and undervoltage protection, to ensure the system’s reliability and safety.
Additional Recommendations:
Refer to the NVIDIA Jetson AGX Orin Series Product Design Guide (DG): This document provides detailed guidelines for designing a carrier board for the Jetson AGX Orin series, including power design considerations.
Consult the Jetson Orin Developer Kit Carrier Board Schematics: Study the schematics of the Jetson Orin Developer Kit Carrier Board to understand the power design and implementation.
Use the TOPO (Software) for Board Automation: TOPO is an integrated board automation solution that can help you design and validate your carrier board.
By focusing on the essential power design aspects and ignoring the irrelevant sections, you can create a reliable and efficient carrier board for the NVIDIA Jetson Orin AGX 64GB module with a 12V DC input.
