PCIe MiniCard Socket
The baseboard is equipped with one Mini PCIe Socket that supports full-size modules.
Two threaded spacers are mounted on the board for installing a full-size module. A USB 2.0 interface is
provided for plugging-in additional cards for expansion and connectivity. The USB 2.0 port is shared between
the 2x5 Header in the
–which is the default setting, and the PCIe MiniCard socket.
This setting can be switched using the Jumper setting options.
PCI-104 and OneBank PCIe/104 Expansion Interface
Elton baseboard implements the PCI/104 Express (PCIe/104) interface functionalities through the PCI-104
connector and the 3-Bank PCIe/104 connector, respectively.
The PCI bus is realized by using a PCIe-PCI bridge such as the
. It supports both, 5V and 3.3V
logic levels that are configurable with a Jumper.
4 x1 PCIe Gen 2 ports and 2 USB 2.0 ports are exposed via the OneBank connector. The x8 lane PCIe port
from the AGX Xavier Series Module is connected directly to the 2nd and 3rd Banks on the PCIe/104
connector.
USB Ports
The baseboard provides 7x USB 2.0 ports and 2x USB 3.1 ports.
1x USB 2.0 port and 1x USB 3.1 ports are connected to 2x5 USB 3.0 header.
1x USB 2.0 port and 1x USB 3.1 ports are connected to 2x5 USB 3.0 header.
1x USB 2.0 port is muxed between the NimbeLink LTE module and MiniCard socket via Mux.
By default, it is connected to the NimbeLink LTE module and can be switched to the MiniCard socket using
the Jumper option.
1x USB 2.0 port, routed from the AGX Xavier Series Module is connected to SMSC Part No.
2x USB 2.0 ports from USB 2.0 Hub are connected to the 2x5 USB 2.0 header.
2x USB 2.0 ports from USB 2.0 Hub are connected to the PCIe/104 OneBank connector.
PCIe M.2 Socket
The baseboard provides a 2242 (22mm wide and 42mm long) form-factor M.2 PCIe SSD module socket
with four PCIe lanes that are routed from the AGX Xavier Series Module.
UFS and Micro SD Socket
To enhance interoperability between devices, the baseboard supports a Universal Flash Storage (UFS) Card
and MicroSD Card Combo socket with options to insert either or both cards.
Data Acquisition (DAQ) I/O Interface
The baseboard implements DAQ functionality via:
Six Single-Ended (SE) Analog-Digital Converter (ADC) inputs or 3 Differential-Ended (DE)
inputs
Two Digital-to-Analog Converter (DAC) outputs
13 Digital I/Os
through the SAM D51 microcontroller Series Part No.
ATSAMD51J18A
All ADC, DAC, and Digital I/Os are available on the 2x13 header. The SAM microcontroller interfaces the
AGX Xavier Series Module through a Serial Peripheral Interface (SPI) bus.
