A4988 Motor Driver
-Size: 1.5mmX2mm (for RAMPS, ultimaker or other compatible boards)
-Driver current: 2A (it is best to install the heat sink )
-Microstep: 1,1 / 2,1 / 4,1 / 8,1 / 16
-Manufacturing process: made by SMT , higher yield, excellent stability.
-Suitable for stepper motor driver below 8V ~35V, 2A
-Simple microstep and direction control interface
-Can adjust max current output by controlling potentiometer to get higher microstep
-Detection and selection on attenuation mode of automatic current.
-Thermal shutdown circuit, undervoltage lockout, crossover current protection
-Good protection on ground and load short circuit
Only Marlin firmware can demonstrate the full functionality of SKR V1.3.
