CAD $42.99
- 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 to achieve higher step rates
