To utilize the wonders of quality Stepper Motors for your Tinkerer Projects, you will need something to drive that magical smoke into them. Stepper Motor Drivers are the regulators behind the curtain and this DQ542MA Stepper Motor Driver is a 2-phase hybrid stepping motor driver with up to 4A peak. Whether operated from a dedicated CNC Controller Board, or simply from a little microcontroller like an Arduino Board, the DQ542MA Stepper Motor Driver is the device to convert pulse signals from a controller into motor motion and achieve precise positioning for high voltage Stepper Motors.
Built to offer smooth operation with low noise and vibration, these DQ542MA Stepper Motor Drivers feature impressively high holding torque under high speeds although at the cost of low holding torque when not running. This means that these stepper motors have a positioning accuracy that is ideal for the use in 3D Printers, laser cutting machines, and other automated CNC Projects.
The DQ542MA Stepper Motor Driver comes with an automatic anti-overheating mechanism called a semi-flow function, in which it reduces the current of the circuit to 70% when no signals have been received for 500ms. Additionally, it is recommended to leave about 20mm of space around the unit clear, so as to ensure efficient heat dispersion and to avoid heat-related problems.
The DQ542MA has been designed to work perfectly with the NEMA17, and NEMA23 stepper motors.

DIP Pins SW1 to SW3: DIP Switch Settings Chart
Each different type of motor will have different current input requirements, which is why the SW1, SW2 and SW3 DIP switches are designed to adjust output current. When setting these, try to accommodate your motors’ requirements as closely as possible.

DIP Pins SW5 to SW8: Microsteps Settings Chart:
Micro step resolution is set by SW5, SW6, SW7, and SW8 on the DQ542MA Stepper Motor Driver. These last four DIP switches define the amount of steps that the motor must take per revolution, and essentially dictates the speed and torque as well. The following chart shows all the options available and what settings SW5, SW6, SW7, and SW8 need to be in to achieve desired revolutions-per-minute.
