The stepper motor driver output version (TBD) consists of 4 axis 2.3A 128-micro-step stepper motor drivers with Molex Mini-Fit Jr connectors for the motor connections. The current settings for the drivers can be set using jumpers, when using Nippon Pulse series stepper motors, or with an adjustment port for other motors. Micro-stepping can be changed on the fly with the MSR command (I/O30 to I/O32).

The TBD drivers use ADMD and AGC technology that optimizes the drive current in real-time, improving efficiency, saving energy, and significantly reducing heat dissipation in the motor and driver.
