TB67S109 Motor Driver Module

This stepper motor driver module can be used separately or in combination with a CNC shield. The motor driver is suitable for motors that require higher currents, such as a Nema 23 stepper motor. 

Specifications:

• Voltage range: 10-47V
• Maximum current: 3A per phase (continuous, with cooling) (4A peak)
• Works with 3.3V and 5V signals
• Current limit that can be set with the potentiometer
• Supports full-step, half-step, 1/4-step, 1/8-step, 1/16-step and 1/32-step
• Security built in for high temperatures and high currents
• Comes with cooling block for better cooling
