Nvidia Nano related documentation, resources and other links

An irritating thing about the Nvidia site is that one can come across outdated versions of PDFs etc. via Google but then it's quite hard to find the current version of the document.

On their site, Nvidia usually use fairly readable unversioned links but these redirect to versioned documents somewhere else entirely. E.g. .../dlc/jetson-nano-datasheet currently redirects to .../secure/jetson/Nano/docs/NVIDIA_JetsonNano_DataSheet_v0.7.pdf. People then copy these versioned links, i.e. what shows up in their browser location bar, into their blog entries etc. and after a while they quickly go stale.

The best place to find the most current links is at the Jetson download center and on this topic posted by one of the Nvidia administrators to the Jetson Nano forum.

The forum topic is not being actively updated - however even though the link text may mention a version number, most of the links are unversioned. E.g. "JetPack 4.2 Downloads" links to https://developer.nvidia.com/embedded/jetpack where you'll find the most recent downloads.

On the download center some of the links seem to be versioned and some not - and some things are released in a rather confusing order, e.g. currently (August 1st, 2019) if you search there for "accelerated GStreamer user guide" you'll see that the most resently released version of this document was 28.3.1 - however if you look further down you'll see version 32.1 was released four months earlier. You probably want the 32.1 version. The version numbers for some documents are tied to Nvidia JetPack versions - so 28.3.1 is a minor revision of an older JetPack version while 32.1 is the more recent one.
