Pegasus Astro eXternal Motor Controller

An Ultimate Powerbox v2, Pocket Powerbox Micro & Advance expansion accessory

The external motor controller (in short 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” or “Pocket Powerbox Micro“.

The device does not require a USB cable and can be attached directly to the EXT port of these Powerboxes. It can drive a large bipolar or unipolar stepper motor (up to 2 amps per coil) with high precision.

Microstepping

The controller supports micro-stepping, which can be configured via software to Full, Half, 1/4 step and 1/8 step. This provides additional precision due to higher resolution and a smooth rotation of the stepper motor shaft.

No USB port is required.

You do not have to occupy a USB port as the controller does not require USB connectivity. Just plug the RJ12 port into the EXT port, and the controller will be recognised from the powerbox software. Simple as that!

Protections

The controller is fully protected against under-voltage, overcurrent, and over-temperature events.

Second EXT port available

A second EXT port allows you to daisy chain future equipment or connect your environmental sensor.
