  PAC024 - 4 Channel Stepper Motor Drive Board
  The PAC024 is a fully featured single board computer using Motorola's MC68376 32-bit microcontroller. The board has a rich set of hardware features, including 4 channels of bipolar stepper motor control, to enable it to control a variety of applications. It can be used either as a standalone controller or used via the CANbus or RS485 multidrop serial interface to provide slave capablities to a variety of controllers. On-board addressing allows up to 64 boards to be used on the same bus.
