● Dimension: LWH 20*15*10 mm/ zero.79″*zero.59″*zero.39″
(Identical with the A4988 and DRV8825)
● Most drive present: 1.5A (Default zero.8A)
● Working voltage: 6V-36V, the proposed voltage is 12V
● Help subdivisions: 1, 1/2, 1/Four, 1/eight, 1/16, 1/32, 1/64, 1/128
● Product Course of: 4 layer PCB board
● Within the 64 subdivision or 128 subdivision to have a greater ultra-quiet impact.
Driver present algorithm and its adjustment:
1. Driver present algorithm (two sorts): Rs=zero.1(R100): I out=V ref / zero.5; Rs=zero.22(R220): I out=V ref / 1.1
2. Please DO NOT join the motors when measuring the voltage, or it is easy to burn the drive.
three. Please join each the facility provide and the USB for energy when measuring the voltage.
Four. Minor adjustment for protention meter driver. Modify it once more after measurement to keep away from burning driver by extreme present.
5. To extend the present by rotating the potentiometer clockwise slowly, and anticlockwise to scale back.
Package deal Consists of:
● 5 x LV8729 Driver
● 5 x Warmth Sink
● 1 x Screwdriver DriverLV8729 driver board extensively utilized in 3D Printers Prusa i3 MKS Base 1.three, on X, Y axis corexy machine and different board, quilter than A4988, extra steady, cooler working each on the drivers and the motors..
LV8729 driver module with 128 subdivisions is an effective alternative for Nema stepper motor whose present is lower than 1.5A, which makes motor regular, quiet and exact.
Help subdivisions: 1, 1/2, 1/Four, 1/eight, 1/16, 1/32, 1/64, 1/128. Within the 64 subdivision or 128 subdivision to have a greater ultra-quiet impact, little vibrations and little or no noise.
Please kindly Observe: Please make sure that the connecting route is true, or it’ll most likely burn the driving force chip and controller board. Advocate to do a superb job of cooling for the module.
