SD02C is designed to drive unipolar or bipolar stepper motor, up to 2Amp peak. The board incorporates most of the components for typical stepper motor applications. Stepper motors are famous about machine builders. Most of CNC, 3D printer and servo uses stepper motor due to its stepping and torque properties. But the control is not as easy as DC brush motor where you can simply apply power to it. The stepper motor will require a correct sequence of the drive to rotate it. With SD02C, you just need a minimum interface, the board is ready to be Plug and Use. Simply add in power and a stepper motor, this driver is ready to drive the motor. The on board test button will help to verify the connection. Pressing the button will drive the stepper motor in a direction with medium speed. Besides accepting the stepper driver conventional control signal (EN, DIR, and Pulse), there is an additional control option, UART or serial. With the UART interface, it can be controlled from computer via USB to Serial bridge such as UC00A. We have even had a GUI in VB for you to test it. SD02C is actually driving stepper motor in the bipolar method. However, since the unipolar (6-lead type) stepper motor can also be used as the bi-polar stepper motor, thus this driver can be used to drive both unipolar and bipolar stepper motor.
