The LV8729 is a PWM current-controlled microstep bipolar stepping motor driver designed for precise and quiet motor operation. It can drive by the CLK input and offers a wide range of operating voltages from 6V to 36V, with 12V being the recommended voltage. The driver supports subdivisions of 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, and 1/128, providing flexibility in motor control.
It is crucial to ensure the correct connecting direction to prevent damage to the driver chip and controller board. Adequate cooling, such as adding a heatsink and using a large fan, is recommended to maintain optimal performance.
Driver Current Algorithm and Adjustment:
- i=Vref/0.5, default Vref is about 0.4V
- Default current: 0.8A, maximum current: 1.5A
- Avoid connecting motors when measuring voltage to prevent damage
- Minor adjustments for potentiometer driver
Package Includes:
- 1 x LV8729 4-layer Substrate Stepper Motor Driver Module
