[Hardware] Clarification on J15 Fan connector type (1.25mm pitch vs 2.54mm?)

Good morning all,

I am currently developping a customised fan for a Jetson Nano application.


While looking through the official documentation, I understand from NVIDIA that the J15 connector has a 1.25mm pitch between two consecutive pins.

Digging further from the jetson nano carrier BOM, I recovered the connector part (2WBA2542WVC-F-04PNLBT1N00G) and while looking on the manufacturer website with I found that it is a 2.54mm pitch

Could you please clarify ?

Many thanks

It’s 2.54mm pitch. Can you tell which doc is it? I don’t see 1.25mm pitch info in devkit user guide doc: https://developer.nvidia.com/embedded/dlc/Jetson_Nano_Developer_Kit_User_Guide

Thank you for the quick reply.

Yes sure here is the reference of the document
NVIDIA Jetson Nano Developer Kit
Carrier Board P3449_B01/ SP-09732-001_v1.1 | January 2020

Please refer to the latest doc in DLC.
