Feature

●✅ A4988 is a complete micro-stepping motor driver with a built-in converter, easy to operate
●✅ A4988 can operate dual stepper motors in full, half, 1/4, 1/8, and 1/16 stepper modes, Output drive capacity of up to 35 V and ± 1A
●✅ Protection function, the stepper motor drive modules can provide Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
●✅ Intelligent chopping control, Chopping control within A4988 can automatically select the current decay mode(fast decay or slow decay)
●✅ As long as a pulse is input into the "Step" input, the motor can be driven to generate micro steps. No phase sequence table, high frequency control line or complex interface programming is required
