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.

@Jurgen,
Ah, very nice! Thanks for that. That makes it easier to use than the massive dev board that the TX1 comes with.
Hi Tony,
we are producing more J120 rev 2 systems this week to fulfill the outstanding orders. So your J120 will ship latest at the beginning of next week.
Best regards, Jurgen
Hi Randy,
1. the J120 carrier board has a level translator to 3.3V. So just connect a standard USB to TTL (3.3V) adapter.
2. a 2 to 4 cell Lipo is fine. The input range is 7V to 17V. However there might be an issue connecting the Lipo Battery directly. As it can supply high current, the voltage to the TX1 builds up very fast. Some TX1 modules do not like that and do not boot. They require the power up edge of the power supply to be slowed down a little. A quick fix is to attach a 470uF 35V capacitor at the J120 power input.
A voltage higher than 17V may damage the J120 and the TX1.
Best regards, Jurgen
Jurgen,
Sorry to be lazy but I've started poking around with my J120 board. Can you tell me a couple of things:
1. what's the voltage of the UART0? I see from the TX1 datasheet that it's 1.8V but I'm wondering/hoping that the carrier board might have level shifted that to 3.3V?
2. I guess I need to power this with a 12V input. Does that need to be regulated or could I be a madman and just directly connect it to my drone's lipo battery? :-)
Thanks in advance.
I will document how to enable the SPI bus on the TX1 in the technical reference manuals of the J100 and the J120. Here is a screenshot of graphical application (QT) to visualize the operation of the IMU.
We now have successfully tested the 9 axis IMU (MPU-9250) which is connected to the SPI bus 0 of the Jetson TX1. I must say, that this was quite a challenge as the SPI bus was not really documented well. It works on both the J100 rev 2 and the J120 rev 1.
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.
@ 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.
