The Ultra quiet LV8729  4-layer Substrate Stepper Motor Driver Module with 128 subdivisions is a Best suited Motor Driver for Nema stepper motor whose current is less than 1.5A, which makes the motor steady, quiet, and precise.

The LV8729 is a PWM current-controlled micro step bipolar stepping motor driver. This driver can perform eight times of excitation of the second phase to 32W1-second phase and can drive simply by the CLK input.

It has a wide range of Operating voltage range i.e. 6V-36V, the proposed voltage is 12V Support subdivisions of 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 with product Process of four-layer PCB board. In the 64 subdivision or 128 subdivision controller, it has a better ultra-quiet effect.

Features:

  • In 64 subdivisions or 128 subdivisions to achieve a better ultra-quiet effect.
  • Operating voltage: 6V-36V, the proposed voltage is 12V.
  • The maximum current is 1.5A, the default is 0.8A.
  • Segment: 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128.
  • You must add the heat sink to make the heat dissipation better (please be sure to operate with a large fan to help to cool the Module).

Driver current algorithm and its adjustment:

  1. Driver current algorithm: i=Vref/0.5, the default Vref about 0.4V, so the default current 0.8A, and maximum current 1.5A
  2. Please DO NOT connect the motors when measuring the voltage, or it’s easy to burn the drive.
  3. Please connect both the power supply and the USB for power when measuring the voltage.
  4. Minor adjustment for potentiometer driver. Adjust it again after measurement to avoid burning driver by excessive current.
  5. To increase the current by rotating the potentiometer clockwise slowly, and anticlockwise to reduce.

Package Includes:

  • 1 x LV8729  4-layer Substrate Stepper Motor Driver Module
  • 1 x Heatsink

Note:

  • Please make sure the connecting direction is right, or it will probably burn the driver chip and controller board. Recommend to do a good job of cooling for the module.
