LV8729 driver module with 128 subdivisions is a good choice for Nema stepper motor whose current is less than 1.5A, which makes motor steady, quiet and precise.
|Dimensions||1.5mm * 2.0mm (Same with the A4988 and DRV8825)|
|Maximum Drive Current||1.5A (Default 0.8A)|
|Operating Voltage||6V-36V, the proposed voltage is 12V|
|Support Subdivisions||1, ½, ¼, ⅛, 1/16, 1/32, 1/64, 1/128|
|Product Process||four layer PCB board|
Motor Current Setting¶
Current limits can be adjusted by measuring the VREF and the adjustable resistance (pls check wiring diagram). Connect the voltmeter + to VREF, [-] to the GND and read the value. LV8729 uses 0.10ohm current sense resistor, so the current limits can be calculated as follows: [Current Limit = VREF x 2]
Please do not exceed the current rating of the motor current, or motor and motor driver will be over-heated, or even damage.
