Stepper Frequency Controller Board, B Knob Tuning, Direction Buttons, Terminal Wiring, Panel Install PCB, Mount Holes

Organized Wiring Points: Screw terminal blocks and a board header keep power and control orderly, making installation cleaner for prototype fixtures and control panels Practical Electrical Specs: Supports 9-24V input and standard 5V output for compact driver control in fixtures, panels, and prototype builds Direct Driver Control: Built to send control output for stepper driver wiring and setup, this board gives users a hands-on way to manage speed and direction from the PCB Knob Tuning: The large front knob supports stepless speed control, while dedicated forward and reverse buttons help confirm travel direction during driver checks Secure Mounting Design: Four corner holes fixed installation on plates, enclosures, or work areas, helping keep the PCB secure during repeated driver work
