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

Description
1
GND
Power (GND)
Common system supply and signal ground
2
V
DRIVER
Power
(Supply input)
Stepper driver supply voltage. Without this voltage stepper
driver ICs and therefore any motor connected will not be
energized
3
V
DIGITAL
Power
(Supply input)
Supply voltage for everything else apart from the stepper
motor driver ICs. On-board voltage regulator will generate
the necessary voltages for the digital circuits from this
supply. This pin can be left unconnected. In this case a
diode between V
DRIVER
and V
DIGITAL
will ensure supply of the
digital parts.
Please note:
- The diode has a current rating of 3A. As V
DIGTIAL
is
available at the I/O connectors and 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of current is withdrawn from these pins for external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).

4.3.2 I/O connector 0
The module offers two I/O connectors. The number and type of inputs, outputs and supply is the same for both
connectors. Therefore, if only half of the inputs / outputs etc. is required it will be sufficient to use just one of
the two connectors and reduce / simplify cabling. Connector type is JST PH series 8pin with 2mm pitch.
