The MXA 087 is the first in a new generation of Pulse Width Modulated DC Motor Controllers.
This module offers the same features as MXA067 but with digital control and display to facilitate a simplified user interface.  3 levels of preset speed control can be selected for repeatable motor performance.  As in the others in the MXA PWM series, MOSFETs are used as the average current control switchers.  Improved MOSFET drivers greatly increase working efficiency of the circuit.

A radical improvemnt over many DC controllers is the MXA087 1 second soft-start .
feature which reduces strain on the modor and the PWM driving it.
