Chapter 4. Modular Connector
4.1 Module Connector Details
Jetson Nano modules connect to the carrier board using a 260-pin SO-DIMM connector. The
mating connector used on the Developer Kit carrier board is listed in the Jetson Nano SCL
(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.
4.2 Module to Mounting Hardware
The Jetson Nano 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 Developer Kit uses
threaded standoffs that are hex, 4.5 mm widths (narrow diameter) x 6.57 ± 0.1 mm length.
These have M.2.5 threads. The screws used are M2.5 x 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.
