Pegasus Astro External Motor Controller

The Pegasus Astro External Motor Controller is a great expansion accessory for the “Ultimate Powerbox v2” and the Pocket Powerbox Advance. The external motor controller is 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.
