Embedding NVIDIA’s Jetson

Embedding NVIDIA’s Jetson

The Jetson family of modules can find homes in a wide variety of systems, bringing low-power machine learning to embedded applications.

Machine learning (ML) continues to garner lots of designers’ mind share, and lots of hardware and software has been delivered to make developers’ jobs easier. NVIDIA is one of the companies at the forefront of this wave, so it’s not surprising that CEO Jenson Huang spent the entire keynote for this year’s NVIDIA GTC 2019 talking about the company’s new ML hardware and software solutions.

The bulk of the keynote addressed high-end ML support like Amazon’s AWS using the latest T4 GPUs to partnerships with Toyota. Squeezed in at the end was the announcement of the Nano Developer Kit and Jetson Nano module (Fig. 1). To me, this announcement was the most significant because the Jetson family is how most NVIDIA ML applications will be deployed.

1. At GTC 2019, NVIDIA's Jenson Huang introduced the Jetson Nano Developer Kit (left) and Jetson Nano module (right), the smallest Jetson family module.

Yes, many cloud-based solutions will be used as well, and there’s lots of money involved. But putting artificial intelligence (AI) on the edge requires platforms like the Jetson family, which now includes the Jetson Nano, TX1, TX2, and AGX Xavier. These provide scalable performance, allowing developers to select modules based on size, power requirements, and performance.

The trick is that the modules can’t be used alone. NVIDIA doesn’t sell the chips alone, only in these modules, so a carrier board is needed to host the modules. As it turns out, quite a few vendors are delivering products that support the Jetson series. This was readily apparent at this year’s Embedded Tech Trends, the Embedded World conference in Germany, and the GTC 2019 in San Jose.

A good example of this support is Diamond Systems’ Ziggy (Fig. 2), which supports the Jetson TX1 and TX2 modules. The Jetson TX1 and TX2 have the same form factor with difference costs and performance characteristics. The Jetson Nano and Jetson AGX Xavier work with different connectors and have different form factors, requiring different carrier boards.

2. Ziggy, developed by Diamond Systems, can support a Jetson TX1 or TX2.

Diamond Systems does have an adapter for the Jetson AGX Xavier called Stevie. This fits between the module and a carrier like the Ziggy that supports the Jetson TX1/TX2 form factor. Developers starting from scratch with the Jetson AGX Xavier are more likely to prefer Diamond Systems’ Elton (Fig. 3). The Elton is a PCe/104 carrier board that allows developers to mate a range of PCIe/104 boards to the Elton.

Many embedded-systems designers will be placing their systems into custom cases. However, Diamond Systems has the ZiggyBox (Fig. 4) for those who require the typical collection of interfaces without the need for major expansion options.

As noted, Diamond Systems isn’t the only vendor supporting the Jetson family. I don’t have enough space here to present an exhaustive list of modules, although I suspect a list might be hidden on NVIDIA’s website.

Other carrier boards I’ve seen are Gumstix's AeroCore 2 for NVIDIA Jetson and Connect Tech’s Sprocket for the Jetson TX1/TX2. Connect Tech has multiple carrier boards and cases providing different interfaces and form factors for the entire Jetson family, including the Jetson Nano. Their Jetson Nano-Pac (Fig. 5) provides free 3D-printing files to match the carrier boards they have available.

Aaeon’s Boxer-8120AI hosts a Jetson TX2 and a four-port switch (Fig. 6). It also exposes a pair of USB 3.0 ports and a USB OTG port plus wireless antenna sockets. It’s designed for rugged environments with an aluminum chassis with anti-dust protection. The system comes with the Jetson TX2 module.

If you’re looking for really rugged designs, then check out Aitech’s industrial A176 and military A77 Twister (Fig. 7). It comes integrated with RedHawk Linux with hard real-time support. The conduction-cooled systems are sealed with rugged connectors.

Aitech isn’t alone in the rugged industrial/military space with Jetson support. Curtiss-Wright’s Parvus DuraCOR 312 (Fig. 8) is also conduction-cooled and has space for a range of flash storage options. It can support eMMC, M.2, and removable 2.5-in. SATA SSD drives. It’s designed for 28-V dc MIL-1275/704/DO-160 power supplies found in aircraft and ground vehicles.

The list could go on, but I’ll wrap up with AverMedia, which supplies a number of Jetson solutions including one for the Mini-ITX form factor (Fig. 9). The EX711-AA has a pair of full-height, Mini-PCIe slots, two HDMI-to-MIPI converters, a pair of USB 3.0 ports, SATA and SD card support, plus dual HDMI outputs. It’s designed to handle multiple video inputs as well.
