Product Description
Longruner A4988 Stepstick Stepper Motor Driver Module + Heat Sink for 3d Printer Reprap (Pack of 5 Pcs)
- A4988 driver board widely used in 3D printers and small CNC machines
- Simple step and direction control interface
- Thermal protection, over-current protection, ground fault protection
- Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
- Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage toachieve higher step rates
-Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) -Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection -Automatic current decay mode detection / selection -Internal UVLO -Mixed with slow current decay modes -Synchronous rectification for low power dissipation -Crossover-current protection -Thermal shutdown circuitry -3.3 and 5 V compatible logic supply -Thermal shutdown circuitry -Ground Fault Circuit -Load short-circuit protection -Of five optional step mode: full, 1/2, 1/4, 1/8 and 1/16 Package Included: 5*A4988 StepStick Stepper Motor Diver Module 5*Heat Sink
