Pinout Description

Pinout description top side

J1 – Power jack

Barrel plug.

12V Input, please use a high quality power supply for stable operation.

J2 – Power port

Molex MicroFit 3.0 (alternative power input)

J3 – USB3

Description

Socket pin

Note

J4 – Ethernet

RJ45

Standard pinout.

J5 – CAM_LED

Please note that on REV 2 and below the J5 and J28 label printed on the PCB is swapped, this mistake is fixed in newer revisions.

Q13 (pin 3) is not over current protected (Max 3.7A).

Set GPIO35_PWM3 too low to activate Q13 (pin3).

As you can see, you can control the J5 pin 3 with three options.

The CAM1 and CAM2 control are intended to be set by your camera device

J6 – CAN1

JST-GH 1.25 mm

CAN1 is RX/TX only and is not outputting power

J7 – I2C

PicoBlade 1.25 mm

J8 – FAN

PicoBlade 1.25 mm

For the use of a 5V fan, there is an option to resolder a component appropriately.

J10 – Debug port

JST-GH 1.25 mm

J11 – HDMI

Standard pinout, connected to DP-2

J12 – CAN0

JST-GH 1.25 mm

You can set a solder ball to enable 120Ohm Termination resistor as shown in the picture below.

J14 – MCU

JST-GH 1.25 mm

With the AI model of the X221 you have access to the safety MCU features. Please contact Auvidea for more information.

The basic MCU of the non AI models only handle power up functionality.

J15 – 2x USB 3.1

Nexus-3815RFY

Standard pinout (type A).

10Gb/s.

Power can be Enabled/Disabled with GPIO22

J17 – MICRO USB

Standard pinout.

Host and device mode supported.

Alternatively, you can use the J29 connector, using the same pins.

J19 – CSI-2

Per special request, Auvidea can manufacture the board with CAM1_PWDN and CAM2_PWDN with pull up to 1.8V.

J20 – PCIe x4

J22 – ETHERNET

Standard pinout.

J24 – CSI-1

Per special request, Auvidea can manufacture the board with CAM1_PWDN and CAM2_PWDN with pull up to 1.8V.

CSI default voltage is 3.3V, but it can be changed to 5V. To perform this modification, you need to move the bead from the 3.3V location (marked with the number 3 as shown in the picture) to the 5V location (marked with the number 5 as shown in the picture).

The same process applies to I2C, where you must move two beads to the desired location of 1.8 (1.8V) or 3.3 (3.3V).

This modification should be performed with care and some good soldering skills.

Auvidea does not cover damages inflicted by poorly performed modifications.

Please contact Auvidea for custom configurations.

J28 – SPI

SM08B-GHS-TB

Please note that on REV 2 and below the J5 and J8 label printed on the PCB is swapped, this mistake is fixed in newer revisions.

J33 – I2C

J37 – PCIe x1

J38 – VCC_SRC

5A total

J39 – USB2

This functionality is not available in standard configuration.

Per special request, Auvidea can manufacture the board with this function.

J41 – USB2

This functionality is not available in standard configuration (only AI version).
