  • What is inside the Xhorse VVDI Prog Hardware?

     Xhorse VVDI Prog programmer is an interesting device carrying out some quite advanced attacks.

    Here comes the 2021 hardware review.

    Disclaimer: Credit to the contributor cyber gibbons.  The review here is for sharing purpose. We are not holding the responsibility if cause damage by disassembling the vvdi-prog..

    The vvdi-prog  has arrived.

    DIP socket is for EEPROMs and SPI flash – it can read a lot of the common ones in socket or via a clip.

    xhorse-vvdi-prog-hardware-review-2

    It’s actually really quite polished, and significantly above average in build quality and design. Strong plastics.

    The MCU stuff comes off this DB25 connector on the end.

    xhorse-vvdi-prog-hardware-review-4

    On opening it, a largely single-sided board. Recent date. Very clean inside, no flux residue.

    xhorse-vvdi-prog-hardware-review-5

    Interesting inside. An STM32 and a ProASIC. Power supply section looks like thought has gone into it. Loads of diodes, probably for protection in the automotive environment. No sure what the lithium cell is doing.

    xhorse-vvdi-prog-hardware-review-6

    STM32F407. One of the most common chips out there.

    xhorse-vvdi-prog-hardware-review-7
    Can’t quite work out the specific part, but it’s a ProASIC3 FPGA.
    xhorse-vvdi-prog-hardware-review-8
     There’s one LQFN 32 that I has had the part number badly scratched off it.

    Not sure on this. 4 pins and 3 pins tied together, thick tracks. Probably switching or regulating.
    xhorse-vvdi-prog-hardware-review-10

    A K-Line bus driver, probably for interacting with certain ECUs.

    xhorse-vvdi-prog-hardware-review-11

    NXP chip

    xhorse-vvdi-prog-hardware-review-12

    that’s a SWD header for the STM32 up there.

    xhorse-vvdi-prog-hardware-review-13

    A header for the ProASIC… not worked with these

    xhorse-vvdi-prog-hardware-review-14

    Protection diodes – not cheap to do this stuff.

    xhorse-vvdi-prog-hardware-review-15

    It takes 12V and can supply a decent amount of current for some ECUs.

    xhorse-vvdi-prog-hardware-review-16

    Comes with a series of cables. Braided, sleeved. Nice quality.

    xhorse-vvdi-prog-hardware-review-17

    Some active components inside… and hot snot. Not sure what the chip is.

    xhorse-vvdi-prog-hardware-review-18

    This ECU one is a bit more interesting.

    xhorse-vvdi-prog-hardware-review-19

    Four of each for ground and power – I think this is for powering bigger ECUs like BCMs and immobilisers.

    xhorse-vvdi-prog-hardware-review-20

    CAN, K-Line, ignition and boot mode come as signals.

    xhorse-vvdi-prog-hardware-review-21

    Again, some active components inside.

    Xhorse vvdiprog is a complex product. Certainly not just something the a TL866 in another box. A device that bypasses security on a range of devices!
