Xhorse VVDI Prog 2021 Hardware Review

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

 

 

Here comes the 2021 hardware review.

The vvdi-prog  has arrived.

Xhorse Vvdi Prog 2021 Review 1

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.

Xhorse Vvdi Prog Hardware Review 3

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.
Xhorse Vvdi Prog Hardware Review 9
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!
