3. FUNCTIONAL OVERVIEW
The following section provides functional details of the key sub-systems implemented on the baseboard.
Processor Modules
The baseboard currently supports the Jetson
™ Series AGX Xavier Modules.
Both series, the AGX Xavier and Xavier 8 GB Modules integrate 512-core NVIDIA Volta GPU with Tensor
Cores, and offer 16 GB of 256-bit LPDDR4x memory with 137 GB/s of bandwidth at 2133 MHz bus speeds
that enable AI-powered platform tools to process high resolution computing tasks at 20 to 32 Tera Operations
Per Second (TOPS) respectively.
The modules encapsulate a high-density 699-pin board-to-board connector for breaking out high-speed I/O
signals to carrier board systems This enables seamless integration of applications and devices across a
wide range of products and form-factors.
Power Supply Specifications
Elton baseboard is powered by a wide input voltage range of +9V to +20V.
Alternatively, the baseboard can be powered from a +12V input source on the PCIe/104 or PCI-04 power
supply board by mounting the Jumper at location 5 on
JP3
. This disables the 5V and 3.3V power feed from
the Elton baseboard to the PCIe/104 or PCI-104 Cards.
NOTE
: The 12V pins on the PCI-104 connector are powered by the main input voltage. To meet the PCI-
104 module I/O card requirements of 12V, the main input voltage supply unit must operate at
+12V.
Power supply voltages for the baseboard are derived from the +(9V-20V) input source. The power supply
unit must meet standards that support the highest bandwidth of on-board memory with additional reserves
to support the add-on features listed in the table below.

Backup Battery
The baseboard contains an on-board RTC (Real-Time Clock) battery holder which accommodates a BR-
2032/BN coin cell. The default board configuration includes an installed coin cell. A 2 x1 input connector is
provided to enable the use of an external battery for rugged applications.
