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. Stepper motor will require correct sequence of drive to rotate it.
With SD02C, you just need 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 have a GUI in VB for you to test it.
SD02C is actually driving stepper motor in bipolar method. However, since unipolar (6-lead type) stepper motor can also be used as bi-polar stepper motor, thus this driver can be used to drive both unipolar and bipolar stepper motor.
Support up to 1.8A (peak) per phase, 1A (continuous) per phase.
Selectable via on board DIP switch
1, 2, 4 and 8 microstepping
Able to drive stepper motor from 6V to 20V
Single power source operation
5V logic level compatible inputs
Control input: Conventional: EN, DIR, PULSES; UART; Test button.
Maximum speed up to 1kHz of pulses (also depends on stepper motor's performance)
Enable/Disable pin for low power consumption mode.
No heatsink or fan required.
Comes with UART (serial) interface, control from computer is possible
UART baud rate are saved in the non-volatile flash memory (Factory default is baud rate = 9600)
By using the UART interface, user can:
On/Off, Run/Brake and change motor’s rotation direction
Set motor speed
Request for encoder value
Track an encoder value and brake the motor
Set new baud rate for the driver
Sample source code for UART control is provided!
Dimension: 7.4 cm x 6.6 cm
