TB67S109 Stepper Motor Driver Module [9V-50V] [4A]

Description:
The TB67S109A is a two-phase bipolar stepping motor driver that uses a PWM chopper. It employs four layers of thick copper precipitation PCB with automatic patch processing. It can drive 57 stepper motors. It uses the indexer (DIR/STEP) control interface. The built-in error detection circuit in chip includes the thermal shutdown (TSD), over-current shutdown (ISD), and power-on reset (POR). This stepper motor driver module can be used separately or in combination with a CNC or 3D printer shield. This driver is suitable for motors that require higher currents, such as a Nema 23 stepper motor.

Note:
1. Be sure to install the heatsink and air cooling. Do not run the module without cooling for long time use.
2. Turn off the power supply when you plug/unplug the driver.
3. Be sure the heatsink is not in contact with the driver pin or any other conductive position.
