Aetina introduces fanless NVIDIA Jetson Orin embedded box PCs with Ubuntu 20.04

Aetina has launched fanless edge AI embedded box PCs powered by NVIDIA Jetson Orin system-on-modules (SoM), namely the AIE-CN31/41, AIE-CO21/31, AIE-PN32/42, and AIE-PO22/32 models featuring the Orin NX or Orin Nano modules, and the AIE-PX11/12/21/22 and AIE-PX13/23 embedded systems fitted with the more powerful Jetson AGX Orin module. All new fanless Ubuntu 20.04 embedded computers are suitable for AI-powered applications and work in an operating temperature range of -25°C to +55°C.

When I first read the email press release, I thought it was a refresh of an old PR since I had written about Aetina NVIDIA Jetson Orin Nano and Orin NX edge embedded systems last January. But those are new models with similar specifications, but housed in a fanless enclosure with a large heatsink, while variants unveiled at CES 2023 were all actively cooled.

Aetina fanless vs actively cooled Jetson Orin embedded box pc
Existing actively cooled model (top) vs new fanless model (bottom)

All embedded box PCs run Ubuntu 20.04 as part of the NVIDIA JetPack SDK and support the various machine learning and artificial intelligence SDKs provided by NVIDIA. The new fanless models have the same specifications as the actively-cooled ones introduced in January, so they may last longer in industrial environments with plenty of dust, consume a little less since a fan is not required, and also operates more quietly although I’m not sure it’s that important for this type of hardware. So the main reason to still use the actively cooled embedded systems from Aetina is the wider temperature range from -25°C to +70°C, while the fanless systems are not guaranteed to work properly over +55°C. The fanless model also appears to lack the RS232 DB9 port for some unknown reason and is taller.

More details about the new fanless NVIDIA Jetson Orin embedded box PCs maybe be found on the products page.

I love how all these vendor images are still based on Ubuntu 20.04 a year and a half after 22.04 was released

> The problem is they need to update the drivers for the AI blocks and it takes a lot of time.

That’s kernel stuff but the Ubuntu release is userland.

It takes little to no efforts to swap the userland while staying with even the crappiest BSP kernel/drivers (BTDT many times manually). And by adopting build scripts (like e.g. Armbian) this could be even automated. Asides that Armbian provides Ubuntu Jammy and Debian Bookworm with 6.1 LTS for Jetson Nano

Even more ‘funny’ is older Nvidia devices being abandoned on a 4.9.299 kernel (the 4.9 series went EOL with 4.9.337 half a year ago).

On the other hand what is the purpose of running such an ARM device when all the IP blocks that really make up the HW (in this case the AI stuff) are not working with a more modern kernel (I guess that’s the case with Armbian’s 6.1 images for Jetson Nano?)
