    Schematic:
    – is this available in a format other than PDF (ie. are the original CAD files available? Orcad?)? Ideally an Altium version would be very useful!
    – The schematic appears incomplete, with various components missing, link wires ending in mid-air. Is this an error or intentional?

    Many thanks!

    To those familiar with the schematics, any notable changes between v1.2 and v1.3?

    – Added a PCIe reset pulldown.
    – Added a GPIO controled heartbeat LED.
    – Added a console UART 3P header.
    – Changed the location of power LED to the middle of the board.
    – Changed the position of MicroUSB connector from bottom to top.
    – Changed the DIP switches to a 20P header connector.
    – Changed the fan header housing to 3-pin compatible.
    – Changed the USB3 connector orientation from horizontal to vertical.
    – Changed the location of JTAG connector to inner side.
    – Changed the projection length of SFP+ cage to same level of RJ45.
    – Changed the voltage of VDDO_H from 1.8V to 3.3V.
    – Removed the console UART level shifter.
    – Removed the MoChi connector.
    – Removed the switch circuit for DDR-IO power.
    – Removed the shunt resisters for AP806 0.9V and DDR 1.2V.
    – Added an alternative DC/DC converter circuit for AP806 0.9V. (second source option)
    – Added an optional signal bypass route to exclude 88×3310.

    I suppose that drivers must check the board revison to toggle the heartbeat LED.

    And
    – Added two 59mm diagonal mounting holes for heatshink or fan.

    Thanks, nanasi! Useful changes all around; the microUSB-vs-USB positioning was particularly conflicting — almost dislodged my microUSB with a pendrive on the fist day.

    SolidRun’s PCN (incl. a picture) is available.

    @nanasi, any idea re ‘single shot SKU’ vs ‘double shot SKU’?

    ed: ok, got from the pdf: single-shot is SFP-only for 10Gbe, double-shot preserves the 1.2 connector setup.
