CAN (J10 and J30)
This is the optional CAN connector. It is not used with the J100/J106 and the TX1. This option is reserved for
the TX2 and J106. The CAN Bus is driven by a TJA1051TK/3,118 CAN bus transceiver. It translates CAN0_TX and

Outputs (GPIOs, I2S, SPI) on the M100
The M100 converts the 1.8V level output signals to 3.3V. It uses a bidirectional level converter, which
automatically detects the direction of the signal. For the level conversion to work properly, caution must be
taken, if there is a pull-up resistor on any output. This applies to all outputs including GPIOs and special
function outputs like SPI, I2S. If there are any pull-up resistors on these outputs, they must have more than 50
kOhm. If there is a pull-up resistor with a lower value, than the level converter may determine that the signal
is driven from the outside, and that this pin should be treated as input.
LEDs
The 12V power LED will light up as soon as the power is connected to the M100, independent of whether a
J100/J106 is plugged in. The 2 on-board DC converters only power up if a J100 or J106 is plugged in.

12V Power out (J16)
This is the 12V power out connector. It is the output of the on-board DC converter. The M100-12 has no onboard 12V DC converter. Here the 12V power in and out connectors are connected together.
Power input (J13)
This is the power input connector. The standard version is the M100-42. It features an on-board DC down
(buck) converter which supports an input voltage of 13.5V to 42V. If the input voltage is less then 13.5V the
12V output voltage may not be stable and it will track the input voltage. For most use cases this actually may
be ok, as the Jetson TX1 can operate with a supply voltage down to 7V. The same is true for the DC converters
on the M100 and J100/J106.
The M100-12 is a special low cost version of the M100. Here the 13.5V to 42V in DC down converter is not
populated and the power in and 12V power out rail are shorted together. For this special version the voltage
input range is 7V to 17V. Please note that the J16 power our connector directly supplies the input voltage.
Alternatively power may be provided via the two 1.5mm holes, where cables may be soldered in.
CAN 2 (J10)
This is the CAN connector which is connected to the SPI to CAN controller on the J100 or J106. The CAN Bus is
driven by a TJA1051TK/3,118 CAN bus transceiver.
