This item is a Sherline or Taig stepper motor driver interface and speed controller. It is also known as a pulse controller. This kit includes one stepper motor driver interface and one speed control with forward and reverse capability.
These components will operate any Nema 23 stepper motor.
We include full wiring details. You will need to purchase a separate 6 Amp 12 Volt Power supply with a 3.5 mm power jack to power both boards and your stepper motor. It takes approximately 3o minutes to install. You can purchase power supplies on eBay for around $8.00.
Both boards must be powered simultaneously to prevent the controller board from burning out. We supply 3.5 mm female power jack that you will connect to both boards. When you turn on the power both boards are powered together avoiding any problems.
