Product Details

  • An Ultimate Powerbox v2 and Pocket Powerbox Advance expansion accessory!

    The external motor controller (XMC) was designed to expand the focus capabilities of the “Ultimate Powerbox v2” (supports a 2nd focus controller) and adds focus functionality to the “Pocket Powerbox Advance“. The device does not require a USB cable and can be attached directly to the EXT port of the Powerboxes. It can drive a large bipolar or unipolar stepper motor (up to 2Amps per coil) with high precision.


    Controller support micro-stepping which can be configured via software to Full, Half, 1/4 step and 1/8 step. This provides additional precision and a smooth rotation from the stepper motor.
