4.2.10 I/O connector
The I/O connector offers 8 digital and analog inputs and 8 digital outputs. All inputs are +24V compatible. All
outputs offer open collector driver stages. OUT_0/1/2/3/4/5 can sink up-to 100mA, OUT_6/7 are more powerful
and can drive up to 2A. A standard 2.54mm pitch two row header is used for this connector (refer to Figure
4.8 please).

* The /Shutdown input pin has to be connected to the supply voltage in order to enable the driver stages
for all three stepper motor axes. A jumper between pin 19 and pin 20 can be used to permanently enable
drivers (please refer to section 4.3.5 for detailed information).
