M335 High Performance and Low Cost Microstepping Driver


The M335 is a high performance microstepping driver with low price. The M335 adopts single-chip PWM bipolar sinusoidal chopper to ensure the low vibration and high efficiency. It is suitable for driving 2-phase and 4-phase hybrid stepping motors, so the Nema16-Nema23 stepper motors with a 0.5A-3.5A current will be suitable.

If you are looking for a device with low cost and stable function, this is an excellent choice for you.


M335 Microstepping Driver

Low cost, Non-creeping phenomenon under low speed. Low noise and non-resonant region.

1, 2, 8, 16 adjustable micro step control for more accurate and smoother motor running.

Remain output torque with higher micro step.

Supply voltage up to 30V DC.

Output current up to 3.5A.

Suitable for 2-phase and 4-phase motors.

High speed optoelectronic isolation signal input.

Single-chip PWM bipolar sinusoidal chopper ensures low vibration and high efficiency.

Automatic idle-current reduction.

Protection of power reversal.


Suitable for a variety of small sized automation equipment and instruments, such as: engraving machine, marking machine, cutting machine, laser typesetting, plotters, CNC machine tools, handling the devices.

Suitable for a wide range of stepping motors, from NEMA size 16/17/23.

Power Supply Selection
Voltage Selection

12-24V DC power supply for Nema 16/17 stepper motors.

24-30V DC power supply for Nema 23 stepper motors.

(High (≥ 30V) voltage will burn out the chips or stepper motors!!! Please be careful in choosing power supply.)

Current Selection

Output current of the power supply can be calculated by the following formula

Output current = Rated current of your stepper motors x quantity + 2A

Please SHUT DOWN the power before you plug or unplug the connectors to avoid burning up the board.

M335 Interface Instruction
Electrical Specifications Of M335 Microstepper Driver
Microstep Resolution Setting Microstep resolution is set by SW1, 2 of the DIP switch .Users should first stop drivers working when adjusting the microstep resolution.
Dynamic Current Setting Dynamic output current is set by SW3, 4 of the DIP switch.
Microstep Resolution Setting Microstep resolution is set by SW1, 2 of the DIP switch .Users should first stop drivers working when adjusting the microstep resolution.
Decay Mode Setting With the decay mode from 0% to 100%, the attenuation increases. Users can eliminate the stepper motor locked noise and improve motion stabilization by switch SW5, SW6.
Automatic Half-current Function Output current is automatically switched to 50% after signal pulse stop for about 0.4 seconds (according to the table settings). This can make the motor and drive heating reduction, improved reliability. Theoretically 25% reduction in the heat (heat is proportional to the square of the current).
Signal Interface PUL + and PUL – are the positive and negative terminals to control the pulse signal. DIR + and DIR – are the positive and negative terminals of direction signals. ENA + and ENA – are the positive and negative terminals of enable signals.
Stepper Motor Interface A+ and A- connect with the positive and negative terminal of A phase winding. B+ and B- connect with the positive and negative terminal of B phase winding. You can reverse the motor direction by swapping A, B phase windings.
Supply Voltage Interface DC Power Supply: 12-30V DC.Recommend voltage:24V
Installation The dimension of the driver is 97 x 75 x 35mm . It is recommended to mount the driver vertically to maximize heat sink area.
