eBay TB6560 Stepper Motor Driver Boards

Hi everyone!
I just made a video of the Chinese fake TBA 6560 IC's.
If your order came from china, better to check them, before powering on.

I don't know where you found this information but according to the Toshiba data sheet pin 10 is power ground and pin 6 is signal ground so is not necessarily low impedance.

Pins 1, 17 22 are not ground as you suggest but are torque setting input, initial state sensing output, and excitation mode setting input, respectively.

You should watch the video carefully. We are talking about two different IC's in the same case.
Pins 1, 17 and 22 aren't groun in the real TB6560 but in the fake one. How could it be possible?
The right one marked as a 6560 ic, but it isn't, it is a 8435.
