I would like to drive single stepper motor (2,2A) with TB6560.
There is more different boards on ebay for ex.
. Anyone has experiences with connecting this boards at arduino? Is there any working examples ?

No experience with this specific chip but the interface is CNC standard opto-isolated step and direction.
One pin for direction and one pin for step, send a pulse on step and it moves in the direction defined by the polarity of the direction pin.
It has microstepping as well, which will require that you multiply by this number of steps...

That board takes step and direction signals which is the most common mode of operation for stepper drivers. Here is an example for the Easydriver board that should work for you:

Thank you for help! Will post results when I get package from HK.

The TB6560 is about the only single-chip stepper driver I've seen that can actually
handle 2A or more, due to the package being heatsink-mounted. It will
still run hot, adding some forced-air ventilation may be wise.
Note that many 2.2A motors are only about 1 ohm winding resistance and
the TB6560 itself is 0.7 ohms, so 40% of your power is wasted in the chip.
Normally a high current stepper driver uses discrete MOSFETs and gets
its series resistance down to 0.05 ohms or less, meaning no heatsinking
is needed. However such a driver needs 8 MOSFETs and various ancilliary
components... Gets expensive.
