3 FUNCTIONAL OVERVIEW
The following section provides functional details of the key sub-systems implemented on the baseboard.
3.1 Processor Modules
The baseboard supports Jetson
™ AGX Orin Series modules.
Jetson AGX Orin module with up to 275 TOPS and 8X the performance of the last generation for multiple
concurrent AI inference pipelines, plus high-speed interface support for multiple sensors, Jetson Orin modules
provide the ideal solution for a new age of Robotics. 4nos of M3 4mm standoffs are provided on the module side
for fixing the AGX Orin module.
3.2 Power Supply Specifications
The board can be powered from wide input voltage range of +7V to +20V, typically 18V. Supply input should be
greater than 15 V if PCIe x16 card is being used.
Maximum allowable reflected ripple, measured at the voltage input connector is 50mV p-p.
All required supply voltages for the board derived from the +(7Vto 20V) input. These power supplies are sized to
support the highest capacity on-board memory and have enough reserve capacity to support the below add-on
features.

3.3 Backup Battery
An onboard 2032 vertical coin battery holder is provided. The board can boot and function normally without a backup
battery as well. The backup voltage signal is also connected to IO connector to connect external backup battery for
rugged application. RTC of Orin module backup voltage of 3V with 1.8V to 3.46V max is required.
3.4 Ethernet Ports
The board offers Two ethernet port one supports 1G and other supports the 10G ethernet speed.
10G Ethernet port derived using MGBE interface from Orin module using 10G ethernet PHY. Onboard magnetics
are NOT provided. LED signals provided for Link, Activity, and Speed Indication
The 10/100/1000 Ethernet port is implemented from the RGMII adapter board. Onboard magnetics are NOT
provided. LED signals are provided for Link, Activity, and Speed Indication.
