NVIDIA's press release states that "Jetson TX1 is the first embedded computer designed to process deep neural networks -- computer software that can learn to recognize objects or interpret information." The 3.4x2inch module includes a Tegra X1 ARM Cortex-A57 processor with 256-core NVIDIA Maxwell graphics, 4GB of LPDDR4 memory, 16GB of eMMC storage, 802.11ac WiFi and Bluetooth, and Gigabit Ethernet support.

The Jetson TX1 Development Kit will be available for preorder starting Nov. 12 for $599 in the United States. The kit includes the Jetson TX1 module, a carrier board (pictured below), and a 5MP camera. The stand-alone module will be available in early 2016 (for $299 in bulk).
The Jetson TK1 (not TX1) was released in 2014 to encourage the development of products based on the Tegra K1 processor. However, according to AnandTech, developers were using the Jetson TK1 outright as a production board, choosing to focus on peripheral and software development instead of system hardware development. With the new TX1, all of the I/O connectivity is provided on a carrier board, enabling rapid development on the credit-card sized TX1 module. After development is finished, the TX1 module can be directly deployed in products, such as drones.

@Patrick,
I'm still using a web cam (a Logitech C920 to be precise). We're going to need a global shutter camera soon-ish though.. and I hear that will be a CSI type.
Hello Randy,
did you get the CSI camera working as a standard v4l2 device , or you are using a USB cam ?
Not sure if anyone but me is still reading this but in any case, I've created a little wiki page here on how to connect Jurgen's J120 board+TX1 to the Pixhawk. We're tentatively aiming to do some vision based precision landing next week some time with this setup. I'll be pushing all the info and images so people can recreate it.
By the way, I've put detailed instructions on how I'm setting up my TX1 in this file here within the "OpenKai" repo. Eventually I'll copy these instructions over into the ardupilot Companion repo. "OpenKai" is a vision library written by a guy I work with here in Japan.
Another update, I've created a new TX1 image (v0.8) which, soon after startup creates a wifi access point (called enroute_drone01), starts MAVProxy and connects to a Pixhawk running ardupilot (connect Jurgen's board's UART0 to the Pixhawk's Telemetry1 port and set SERIAL1_BAUD to 921). It also streams wifi from a webcam on port 1234 so you can see this live video from another computer by simply connecting to the TX1's wifi access point and then open a browser and enter the URL as 10.0.1.1:1234.
I've found a couple of small issues - with my early version of the J120 board it doesn't seem possible to upload or download an image to or from the TX1 so I need to disconnect the TX1 and remount it on the original dev board to do that.
There's a low level bootloader on UART0 which means that if a pixhawk is powered up and transmitting MAVLink packets to the J120/TX1 when the TX1 starts up it stops the TX1 from booting up. I've temporarily gotten around this by setting ArduPilot's TELEM_DELAY parameter to 20 so that the Pixhawk doesn't sent any data on that port until after the TX1 has gotten past the bootloader stage.
Overall I'm still very happy with the J120 board.
Minor update, I was able to disable the console on UART0 by doing what Jurgen and DustinF pointed me to above (i.e. edit /boot/extlinux/extlinux.conf and remove the ttyS0 from the list of console). That on it's own didn't resolve the problem but typing "sudo stop ttyS0" worked. I'm not sure if both steps are required or only the 2nd one (the "sudo stop ttyS0"). In any case, I now have my TX1 able to communicate with the Pixhawk using mavproxy. It's very much like the instructions for the RPI2.
It doesn't seem like the flow-control is working between the TX1 and the Pixhawk though so I've had to set the pixhawk/ardupilot's BRD_SER1_CTSRTS parameter to zero to disable the ardupilot side from using flow-control on telem1.
Similar to what we were doing for the RPI2, I'd ideally like to be able to provide TX1 images to help people get started more quickly.
Hello Randy,
Thank you for your reply. The question was related to NVIDIA TX1 development board; the "huge" one as you described. For the first ten flights at least I am planning to use that board. Are you aware about the weight of it? My quad is a Tarot 650 extended to 750mm (motor to motor) with 8kg max thrust and overall weight 2.7Kg with an Intel Atom development board from msc technologies on it. Check the following photo,
I measured my board from Jurgen and it's 11cm long, 5cm wide, 4cm tall. I'm not rounding off those numbers, it's size seems to be nicely rounded units. Most of that height is the heat shield and fan. I'm not sure of the weight but it is a bit heavy, maybe twice the weight of a GoPro?
In case I'm misunderstanding, the NVidia dev board is a monster. 18cm x 17cm x 6cm (?). totally huge, I can't imagine you'd want to put that on a vehicle.
Hi all,
I am planning to mount in a Tarot 650 the TK1 or the TX1 dev boards. Does anybody knows the dimensions and the weight of the TX1 development board?
Hi Randy, here's a link how to disable the kernel log on tty0: https://devtalk.nvidia.com/default/topic/931661/jetson-tx1/disable-...
