Based on TB6560AHQ of Toshiba chip, it is able to manage up to 3-step bipolar or unipolar stepper motors with current of 3 A (3.5 A peak). Dip switches to select control mode: step, half step, 1/8 step, 1/16 step and decay Mode.
Opto-isolated inputs, an output for connecting the relay to control the spindle, it has an interface with 4 inputs for limit switches management of XYZ axes and emergency stop. It can be used with stepper motors unipolar or bipolar 2 or 4 phases (4, 6 or 8 wires) 3A max. Compatible with Mach3 software, Emc2, KCam and all systems of a parallel port.

The package includes the board, 2-wire cable and a parallel cable for connecting to your PC.

Power: 12 to 36 Vdc - 5 A Dimensions: 175x115x20.

N.B. stepper motors and power supply are not included (see related products).
