Ultra-silent 4-layer Substrate MKS-LV8729 Stepper Motor Driver Support 6V-36V With Heatsink For 3D Printer

Descriptions 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 Features 1 In 64 subdivision or 128 subdivision to achieve a better ultra quiet effect 2 Operating voltage 6V 36V the proposed voltage is 12V 3 The maximum current is 1 5A the default is 0 8A 4 Segament 1 1 2 1 4 1 8 1 16 1 32 1 64 1 128 5 You must add the heat sink to make the heat dissipation better please be sure to operate with a large fan to help cooling Specifications Model LV8729Type stepper motor driverSize 1 5mm x 2 0mmMaximum drive current 1 8AMaximum voltage 36V usually 12V Supported segament 1 1 2 1 4 1 8 1 16 1 32 1 64 1 128Product craft four layer PCB boardProduct weight 5gNote 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 5 the default Vref about 0 4V so the default current 0 8A and maximum current 1 5A2 Please DO NOT connect the motors when measuring the voltage or its 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 potent
