Connect the encoder
For boards with assembled encoder option three connectors (one encoder interface connector per axis)
will be available. A standard 2.54mm pitch two row header is used for connecting an encoder.
Differential and single ended incremental encoders with/without zero/index channel are supported.
Please connect the encoders as follows:
-
Single ended encoder: GND to pin 1 and/or 2
+5V to pin 7 and/or 8
A to pin 5
N to pin 3
B to pin 9
-
Differential encoder:
GND to pin 1 and/or 2
+5V to pin 7 and/or 8
A+ to pin 5, A- to pin 6
N+ to pin 3, N- to pin 4
B+ to pin 9, B- to pin 10

Connect the interface
In this case we choose the USB interface for serial communication. A standard USB type B connector
is used for this purpose. USB is one out of four different interfaces available for communication with
the board. You can refer to the hardware manual for further information about the pinning of the
other interfaces.
Please connect the USB interface with the enclosed cable as follows:
