Step motor control Module – Driver A4988

Driver A498 is a stepper motor control module commonly used in CNC systems, 3D printers and projects related to precise motion control. With a compact design, easy stepper motor control and multi-step support (microstepping), A4988 is the first choice for those who work with stepper motors.

* Main specifications
– Logical supply voltage: 3.3V – 5V (compatible with most microcontrollers)
– – Motor voltage (VMOT): 8V – 35V
– – Maximum load current: 2A per coil (with appropriate heat dissipation and cooling system)
– – Adjust current: Yes (via potentiometer on board)
– – Microstepping: Supports micro-step levels 1/1, 1/2, 1/4, 1/8, 1/16
– Dimensions: 20mm x 15mm
– Pulse frequency: Up to 500kHz
The A4988 has the ability to accurately control the stepper motor through micro-step levels, helping the system achieve smooth and precise movement. With features such as current limit and over temperature protection, this driver ensures safety and durability when operating for a long time.
