Sell Step Motor Control Circuit For 3d LV8729 Printer best price

Lv8729 stepper motor driver with A4988 DRV8825 radiator compatible with 3d MKS Gen V1.4 Ramps 1.6 1.4 1.5 printer This LV8729 driver module with 128 split parts is a good choice for Nema stepper motors with a current of less than 1.5A, making the engine stable, quiet and accurate. Product information Size: 1.5mm * 2.0mm (Similar to A4988 and DRV8825) Maximum drive current: 1.8A (Determined 0.8A) Operating voltage: 6V-36V, recommended voltage is 12V Branch support: 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 Product process: four-layer PCB circuit board In the 64-branch or 128-branch controller, there will be a better quiet effect. Note: Please make sure the connection direction is correct, otherwise it may burn the driver chip and the control board. Please assemble the product 1 carefully Driver's power algorithm and adjustment level Driver current formula: I = Vref / (Rs * 5), Rs = 0.22Ohm, Imax = 1.8A -Please Do NOT connect the engine when measuring the voltage, otherwise it is easy to burn the inverter. -Please Connect both the power supply and USB to power supply when measuring voltage. 4. Adjust the potentiometer driver to a small level. Adjust after measurement to avoid burning the driver by excessive current. 5. To increase the current can be done by slowly rotating the potentiometer clockwise and counterclockwise to reduce. Tips for increasing heat dissipation LV8729 Lv8729 uses four layers of PCB to dissipate heat, while the chip is attached to the default heatsink of 1A which means it will actively dissipate heat, such as using a fan, hanging radiator. Or install a large fan for your control board.
