Lv8729 Stepper Motor Driver 4-layer Driver untuk 3D Printer

Specifications:Dimensions: 1.5mm * 2.0mm (Same with the A4988 and DRV8825) Operating voltage: 6V-36V, the proposed voltage is 12V Support subdivisions: 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 Product Process: four layer PCB board In the 64 subdivision or 128 subdivision to have a better ultra-quiet effect. Item Type:Driver Model Number:LV8729 Item Type:Driver Color:Black Material: metal, plastic With heat sink:YES weight:6.8g Condition:NEW Product Name:Lerdge lv8729 Stepper Motor Driver Module 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. 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. Driver current algorithm and its adjustment: 1. Driver current algorithm: i=Vref * 0.9, the default Vref about 0.4V, so the default current 1.2A, and maximum current 2A 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 Contents: 1x lv8729 stepper motor driver moduleOnly the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
