The microUSB slot is used during initial setup and a USB “on the go” adapter lets you then adapt the microUSB to a regular USB 2.0 slot so your keyboard can be connected there, leaving the USB 3.0 port free for more interesting tasks. On the left side of the board next to the Jetson COM, you’ll find a PCIe x4 slot and the SATA and SATA power connectors. The Jetson has most of its connectors on the base board along the back, including a gigabit Ethernet connector, an SD card slot, HDMI, USB 3.0, microUSB, two WIFI antennas, and a DC power input socket. When comparing the Jetson TX1 with desktop and server hardware, however, although the latter can have powerful GPU hardware, the Jetson will likely draw significantly less power.įigure 1: OpenSSL cipher performance speed test.įigure 2: OpenSSL digest performance speed test. The GPU can perform many general-purpose tasks as well as much of the image manipulation and mathematics used in high-end robotics. Any such comparison will quickly lead to moving away from benchmarks that target the CPU only to considering the performance advantage offered by the NVIDIA Maxwell GPU on the Jetson board that is covered later in the article. To help you use all these features, a base board with a mini-ITX form factor is part of the developer kit, and it gives you one USB3 port, a microUSB port for setup, 19-volt DC input for power, HDMI 2.0, SATA, full-sized SD card slot, camera and display connections, two antenna connectors, and access to low-level hardware interaction such as SPI, GPIO, and TWI connections.īecause of the small size of the Jetson TX1, it is tempting to compare it with other small machines like the various Raspberry Pis, BeagleBone Black, and ODroid offerings (Figures 1 and 2). The COM contains all these and physically sits below the aluminum heat sink in the picture. This includes the NVIDIA Maxwell GPU, CPUs, RAM, storage, WiFi handling, etc. The heart of the Jetson is on a computer on a module ( COM ). You might not care about the 4k video streams at a job site, but you want to know if an unknown person is detected in any image at 2am. Whether the Jetson TX1 is driving a screen in a car seat or performing image recognition at a remote location with limited bandwidth - it’s a smarter choice to perform processing on site. Stepping away from robotics specifically, the Jetson TX1 is a very interesting machine when you want to take performance with you. The small size, low power, and great GPU processing of the Jetson TX1 screams for robotics applications where the machine is on the move and needs to process streams of images and sensor data in real time. The SATA interface gave great performance when paired to an SSD, and the two antenna 802.11ac gave speeds up to gigabit Ethernet over the air. And, you have 4GB of RAM and 16GB of eMMC storage, so you should be able to load your application onto the on-board storage and throw around big chunks of data in RAM.
Aside from the GPU, the CPU is certainly not slow with four 64-bit A57 ARM cores. The NVIDIA Jetson TX1 offers enormous GPU processing in a tiny computer that only consumes 5-20 watts of power.
