Connections
Pinout
VCC
Power input. Check whether the module expects 3.3V logic or 5V logic or 8.2V-45V motor supply before wiring.
GND
Common ground with the controller and external supply.
STEP/DIR
Main STEP/DIR connection used by the module.
IO
Additional signal pins depend on the exact module variant.
