The optional super cap is the tallest component on the bottom side (5.5mm high). The capacity of the super
cap is 47mF. Optionally the RTC (realtime clock of the Jetson TX1) may be powered by a Lithium cell
(MS621FE-FL11E). It is located next to the power button. If the super cap and the Lithium cell are not
populated, RTC power may be provided on the buttons connector (J12 pin 1).
Testing of the J130
Please have a look at the test report which is included with the shipment.

Getting started
Applying power
The J130 is powered by the on-board power connector (J14 or optionally J15).Please check the input voltage
requirements for your J130 revision.
Auto start
The J130 automatically powers up the TX1 with a digital one shot which pulls the POWER-BTN input of the TX1
low for approximately 1 second after power is applied. When the TX1 raises the CARRIER_PWR (A48) line, the
power supplies on the J130 are powered up. This is indicated by lighting up the green power LED (PWR D13)
next to the CAN2 connector.
The auto start logic is powered by Vdd_RTC (A50). Rev 1: for auto start to work, please power down the TX1
for a few seconds. This allows time for the auto start power supply to drain and to re-arm it, to enable auto
start, when power is applied again. Alternatively power up the J120 by pressing the power button.
Console access
The console port of the TX1 is UART 0. The J130 converts this UART port to standard 3.3V TTL levels. So a
standard USB to TTL serial converter may be used to connect to the console. Just connect TXD, RXD and GND
to the USB converter. Make sure that you connect TXD to the RXD input of the USB TTL converter. Standard
baud rate it 115200. Settings: 8/1/N. The I/O voltage is 3.3V. Please do not use a pull-up resistor of 50kOhm or
less on the TXD line, as this confuses the bidirectional level converter. It will then assume that the TXD pin is
driven from the outside which will reverse the direction of this signal.
Firmware upgrade of the TX1
The J130 does support a direct firmware upgrade of the TX1. Please put the the TX1 into the upgrade mode
with the recovery button before connecting the USB cable to USB0. Alternatively please perform the firmware
upgrade on the TX1 development board.

Devices
IMU (MPU-9250)
A 9 axis sensor is connected to the SPI0 bus of the TX1. Pin 8 (VddIO) of the IMU is connected to 1.8V. Please
set the INT output of the IMU by software to „totem pole“ mode as there is no pull-up on the INT output.
This IMU is optional. Only some J120 models are equipped with this function.
SPI busses with the Jetson TX1
The Jetson TX1 features 3 SPI busses: SPI0 to SPI2. The table below lists how these SPI devices are mounted.
Please note how the 5 physical SPI devices relate to the 5 spidevs.
Test o f th e I MU w i th t he
RTIMULibDemo
This demo may be downloaded from Github.
Please install qtcreator first. Next please
make sure that the spidev3.0 device in /dev
is loaded. Edit the RTIMUlibDemo.ini file
with the SPI settings for the IMU (bus 3,
select 0). Start the demo as root so it gets
access to the SPI bus.
The IMU chip is located on the bottom side
next to the JTAG connector. The IMU is is
default feature on the J130.

I2C busses with the Jetson TX1
The Jetson TX1 features 7 I2C devices: I2C0 to I2C6. The table below lists how these I2C devices are mounted.
The two Toshiba TC358840 HDMI to CSI-2 converter chips are located on the 7 bit I2C addresses 0x0F and 0x1F,

interfaces, the J130 features 1 SPI based CAN controller (Microchip MCP2515). The second is optional. Please
install the Kernel and support package with the MCP2515 driver, which is provided by Auvidea.

audio channels to I2S and I2S3. In this case the 3 CLKs (I2S_CLK, I2S2_CLK and I2S3_CLK) are shorted together.
Also the 3 word clocks (I2S_LRCLK, I2S2_LRCLK and I2S3_LRCLK) are shorted together. The recommend value is
10 Ohm.!

HDMI input 2 (J17) (up to 1080p60) - address 0x1F
This HDMI input is connected to a Toshiba TC358840 HDMI to CSI-2 bridge chip. It connects via one 4 lane CSI-2
interface to the Jetson TX1 (CSI_AB). The pin numbers below are the pin numbers of the Toshiba chip.
Reset
The HDMI in 1 device features RC components on the reset input (100nF with 10k pull up) to perform an power
up reset. The HDMI in 2 device must be reset by the TX1 GPIO after power up. Only after a reset the second
HDMI in device will be accessible.
Please see the commands below. First only the 0x0F device shows up. Then a reset to the second device is
performed by enabling GPIO 149 as GPIO pin, then setting its direction and last by writing a sequence of 1 - 0
-1 to this output. The low pulse resets the second device.

CAN controller (MCP2515T-I/ML)
The two SPI to CAN controllers add two CAN bus interfaces to the TX1, as there is no internal CAN controller in
the TX1. The SPI bus, RESET and INT are shared between the 2 CAN controllers (J120 rev 1). The J120 rev 2
will use separate SPI interrupts. Just SPI1_CS0 and SPI1_CS1 select one of the two controllers. The two CAN
busses are available on J9 (CAN1) and J10 (CAN2).
CAN controller 1 (not populated):
CAN controller 2:
CAN1 (J9):
This CAN port is reserved to connect to the build-in CAN controller of the TX2. RN29 must be populated. The
CAN0 port of the TX2 connects to the CAN transceiver (TJA1051TK/3). This connects to the CAN connector. The
port is terminated by 120 Ohm.
CAN2 (J10):
The CAN Port connects to the SPI to CAN controller 2.

J130 (38205-X)
UART 0 / UART 2 (J10)
This UART connector features 2 UART interfaces. UART 0 is the console (115200, 8, N, 1). Please note that the
TXD lines should not have a pull up resistors with less than 50k Ohm. A pull up resistor with a low resistance
will make the bidirectional level converter on the J130 assume that this pin is driven by the outside.
FAN (J11)
This is a 4 pin connector with 1.25 mm pitch. This is the same pinout as the fan connector on the Jetson TX1
development kit. With the J100 the fan is on by default. Use the „fan disable“ feature to turn off the fan.
Please note, that the „fan disable“ requires a software change when compared to the dev kit. On the dev kit
„fan disable“ is controlled by an I2C port expander line. On the J100 „fan disable“ is connected to
GPIO19_AUD_RST (through an inverting MOSFET). Pull the GPIO19 (F2) high to disable the fan (pin 4 becomes
low). A low or floating signal on GPIO19 will not disable the fan.
Power (J14) and (J15)
J14 is a 2 pin connector with 5.5/2.5mm. J15 is an optional Molex connector (430450400) with 3mm pitch and
4 pins. Pin 1 and 2 are in the front (+) and pin 3 and 4 in the back (-). Two pins each are shorted together.
