Stepper Motor Driver Board

This series is driven by a stepper motor.
To operate the stepper motor, a dedicated driver board is required.
We offer the following driver board as a separately sold option. Please contact us if needed.
★ To use the driver board, you will need a pump equipped with wiring that includes
a JST connector compatible with the driver board (e.g., RP-HⅢ02*-45A-DC24VS).
