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.
NVIDIA used a drone application to promote the Jetson TX1

Here a 3D rendering of the J120 rev 2:
Changes for rev 2:
- larger M.2 mount holes plus M.2 fix
- aligned RJ45, USB3, and mini HDMI connectors
- drain Vdd_RTC to immediately rearm auto start logic
M.2 SSD with four PCIe lanes on the TX1
We now got the high performance M.2 key M (2280) SSD to work on the J120. First we had to recompile the TX1 Linux, which was a little challenge. We had to compile in the NVME driver. First we tried this on the dev kit. There we used a DeLOCK PCI Express Card > 1x internal M.2 NGFF adapter card (#89370). With this we could read and write the M.2 card. Next we tried it on the J120. There we have discovered a bug in the M.2 power supply. After we patched it we could test it on the J120 rev 1. I worked fine. We are not going to patch the J120 rev 1 boards which we ship out to beta customers. On these the M.2 slot will not be supported.
It will be fixed for the J120 rev 2 which is scheduled to become available in the second half of April.

I have very good experience with VESC version 4.8 for robotics. I am confident it would be perfect for a drone. Benjamin is now working on version 5.0: http://vedder.se/forums/viewtopic.php?f=6&t=149
I chose this esc because of great start-up torque and foc position control. There are some old drone tests from Benjamin but I am not sure they have VESCs inside (or they have an old version): https://youtu.be/aoiuTptnMbY.
@ Jerryno,
I have looked at the VESC motor controller. I like it very much. Do you have some specific experience with this controller in drones?
This weekend I have sat down and entered this design in Altium. I have made changes so it is all SMD. And I have added five 330uF low ESR (120mOhm each) capacitors on the back so they have a very low impedance connection to the MOSFETs. I think that impedance is much more important than capacitance. Does somebody have some experience in this area and could provide some guidance? Here are the images of the 3D renderings in Altium.
My congratulations to Benjamin Vedder. I think, the VESC is a great design.
Here is a picture of the new J120 rev 1. The first boards of the J120 have been sent out. A couple went to enRoute and Nvidia Japan, to be shown at the drone expo. Also Randy has been sent one.
1. I will align all 3 connectors on the left.
2. I will fix the auto start record delay by draining Vdd_RTC
3. I will swap the PCIe busses on the M.2 connector, so that the J120 is fully compatible to the dev kit
First rev 2 samples will become available late April.
Hi Jerryno, sorry the J120 is not open source. It is a commercial product. Designing such a high tech product with so many high speed busses like Gigabit Ethernet, USB 3, CSI-2, PCIe is quite a challenge. Today we have build up the first 8 boards of the J120 rev 1. Within 1 hour we had the Ubuntu desktop up and running. Ethernet and USB 3 and HDMI out seem to be ok. As a first test we played a 4k demo video which really stressed the quad core ARM. I am going to post some pictures tomorrow. Regards, Jurgen
@ Randy, Wait, is the J120 open-source? I think the hardware is closed. But you can definitely count the VESC motor controller which already beats most (I think all) commercial motor controllers. CAN-centric architecture and quiet field oriented control are perfect for any drone.
@Jurgen, That is great new! I will be there and drop by the booth of enRoute.
@Randy, Do you have any plane distribute those board in Japan?
Jurgen,
Yes, I know EnRoute well and I'll actually be a key-note speaker at the conference focusing mostly on explaining how companies can get involved developing and integrating open source systems into their drone products.
If you don't mind, I was actually thinking of inserting this image of your board into my presentation as one of the examples of interesting things that's come out of the open source community.
Here is some more information about the Japan Drone Expo:
