RU Ship 4 Axis CNC Router Kit 4pcs 1 axis TB6560 driver & interface board & 4 Nema23 270Oz-in stepper motor & 350W Power supply In the past I have damaged two EasyDriver at their direction input because I connected them to an Arduino output without to supply first the motor driver board. With the Pololu I haven't any experience, only the datasheet is known. You mentioned the TB6560AHQ and it seems to be the successor of the TA8435HQ with a higher output current.
