3.2.1 Power Connector
The module has a single power connector with the option to have separate supplies for driver
electronics and the digital controller part. A single supply voltage is sufficient. All further voltages
required e.g. for the digital components are generated on-board.

Description
Common system supply and signal ground
Stepper driver supply voltage. Without this voltage
the stepper driver and any motor connected will not
be energized.
Supply voltage for everything else apart from the
stepper motor driver. The on-board voltage regulator
generates the necessary voltages for the digital
circuits from this supply. The pin can be left
unconnected. In this case a diode between V_DRIVER and
V_DIGITAL ensures the supply for the digital parts.
ATTENTION:
- The diode has a current rating of 3A. As V_DIGTIAL is
available at the I/O connectors and at the
reference switch connectors also, always connect
this pin to positive supply voltage in case
substantial amount of current is withdrawn from
these pins for external circuits.
- It is expected that V_DIGITAL and V_DRIVER are connected
to the same power supply output when both pins
are used. Otherwise please ensure that V_DIGITAL is
always equal or higher than V_DRIVER when
connected (due to the diode).
3.2.2 Motor Connector
A 4 pin JST EH series connector is available for motor connection.
