Chapter 5. Modular Connector
5.1 Module Connector Details
Jetson Orin modules connect to the carrier board using a 260-pin SODIMM connector. The
mating connector used on the reference design carrier board is listed in the Jetson Orin NX
and Jetson Orin Nano Supported Components List. This connector is a DDR4 SODIMM, 260-
pin, right-angle, standard key type. The full height of the connector is 9.2 mm. Refer to the
connector specification for details. Other heights are available.
5.2 Module to Mounting Hardware
The Jetson Orin module is installed in the SODIMM connector which has latching mechanisms
to hold the board in place. In addition, it is required that the module is mounted to the main
carrier board PCB using metal standoffs and screws (or equivalent), both for mechanical
integrity and to provide additional grounding points. The recommended standoffs used on the
carrier board are threaded standoffs that are hex, 4.5 mm widths (narrow diameter) × 6.57 ±
0.1 mm length with M2.5 threads (or equivalent). The screws that match the described
standoffs are M2.5 × 3.7 mm, pad head.
Other SODIMM connector heights are available. If a different height connector is used, the
standoff height will have to be adjusted accordingly to account for the difference in height from
main PCB to module PCB.
