A4988 Stepper Motor Driver 3D Printer accessory Drive module board with heat sink
- The A4988 is a complete microstep motor driver with a built-in converter for easy operation. The product can operate dual stepper motors in full, half, 1/4, 1/8 and 1/16 step modes, with output drive performance up to 35V and 1A. The A4988 includes a fixed turn-off time current regulator that operates in slow or mixed attenuation modes. The converter is key to the A4988's ease of implementation. As long as a pulse is entered in the "step" input, the motor can be driven to produce microsteps. There is no need for phase sequence tables, high frequency control lines or complex interface programming. The A4988 interface is ideal for applications where complex microprocessors are unavailable or overloaded.
- The chopper control in the A4988 automatically selects the current decay mode (slow or mixed) during microstep operation. In hybrid attenuation mode, the device is initially set to decay rapidly during part of the fixed downtime and then slowly during the remaining downtime. The hybrid at
