机器学习（ml）继续加入大量设计师的思维份额，并且已经交付了大量的硬件和软件，以使开发人员更容易。nvidia.是这一波浪最前沿的公司之一，所以CEO Jenson Huang在今年的NVIDIA GTC 2019年谈到该公司的新款ML硬件和软件解决方案并不令人惊讶。
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.在GTC 2019年，NVIDIA的Jenson Huang介绍了Jetson Nano Developer Kit（左）和Jetson Nano模块（右），最小的Jetson系列模块。
是的，也将使用许多基于云的解决方案，并且涉及许多资金。但在边缘上放置人工智能（AI）需要像Jetson系列这样的平台，现在包括Jetson Nano，TX1，TX2和Agx Xavier。这些提供可扩展性能，允许开发人员根据尺寸，电源要求和性能选择模块。
诀窍是模块不能单独使用。NVIDIA仅在这些模块中单独销售芯片，因此需要载波托管模块。事实证明，相当多的供应商正在提供支持Jetson系列的产品。这在今年很明显嵌入式技术趋势，德国嵌入式世界会议，以及圣何塞的GTC 2019。
A good example of this support is钻石系统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.由钻石系统开发的Ziggy可以支持Jetson TX1或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.
3. Diamond Systems'ELTON主持NVIDIA Jetson Agx Xavier，允许它与PCE / 104扩展板一起使用。
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.
ZiggyBox隐藏了Jetson Tx1或Tx2的Ziggy载体。
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隐藏在Nvidia的网站上。
Other carrier boards I’ve seen are牙龈适用于NVIDIA Jetson的Aerocore 2和Connect Tech’sSprocketfor 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（图5）provides free 3D-printing files to match the carrier boards they have available.

Aaeon的Boxer-8120AI hosts a Jetson TX2 and a four-port switch（图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.

如果您正在寻找真正坚固的设计，请退房艾特克的industrial A176 and military A77 Twister（图7）。它与RedHawk Linux集成，具有硬实时支持。导通冷却的系统用坚固的连接器密封。

Aitech并不孤单地与Jetson支持崎岖的工业/军事空间。Curtiss-Wright’sParvus DuraCOR 312（图8）也是传导冷却的，具有一系列闪存选项的空间。它可以支持EMMC，M.2和可移动2.5 in。SATA SSD驱动器。它设计用于28-V DC MIL-1275/704 / DO-160电源，在飞机和地面车辆中找到。
8. Curtiss-Wright’s Parvus DuraCOR 312 is available with a number of storage options.
The list could go on, but I’ll wrap up withAvermedia.，它提供了许多Jetson解决方案，包括一个用于迷你ITX的形状因子（图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.
