Manufacturing options

Enclosure

Auvidea can provide custom enclosures for its carrier boards. These enclosures provide a passively cooled solution. This solution is designed for the AGX models. With a max power draw of 35W (normal mode) the enclosure temperature reaches 55 °C while in 24 °C room temperature which is a safe temperature for Human contact. The MaxN mode (up to 90W) is not recommended as the enclosure temperature increases above acceptable levels for direct human contact. It is also possible to apply your branding on the front and backplate of the Enclosure. Auvidea has in-house capabilities of laser and milling engraving.

Branding and QR codes

Besides the branding options for the enclosure, it is also possible to customize the label field on the carrier board. Auvidea uses the label field to engrave a small QR code and serial number to track production processes. It is possible to add your custom engravings like logos, text or QR codes to this field as a laser engraver is used.

Custom configurations

The standard carrier board configuration is designed to suit most use cases. Please see the Pinout description for customization examples like voltage configurations (3.3V or 1.8V).

We take pride in tailoring our products to your special need and are capable to adjust it in small production series. Please contact Auvidea with your special requests to work out a solution.

Frequently Asked Questions

• Why is my X221 not going into force recovery?

  • If your system is not going into force recovery, please contact our support, as you may have got a system with a mismatched firmware.

• Why is my system not entering the force recovery state?

  • Most of our carrier boards are design to enter force recovery mode when they detect a Host PC. This detection only works one time automatically after the system was connected to its power supply. We recommend unplugging your system before connecting to a Host PC and plugging it back in to power after connecting.

  • If your system still does not enter force recovery, you may have to press the force recovery button or short the respective pins before connecting to power (please see the Technical Reference Manual for a detailed pinout description).

  • If you cannot disconnect your system from power, it is also possible to enter force recovery via a button sequence.

    • Press/jumper “force recovery” button/pins

    • Press/jumper “reset” button/pins

    • Release/disconnect “reset” button/pins

    • Release/disconnect “force recovery” button/pins a few seconds later than the “reset” button/pins

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

J2 – Power port

Molex MicroFit 3.0 (alternative power input)

J3 – USB3

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.

Powered by power limiting switch with 500mA.

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.
