The SureStepr lv8728 is a stepper driver board based on the LV8728 chip. Use the Indexer (DIR/STEP) interface to easily use and operate the stepper motor. LV8728 is a drop-in alternative to Pololu-style footprint drivers such as SD8825, A4988, A4983, Step Stick. One of the features of the LV8728 is that the heat pad is placed on the top of the chip. This makes the heatsink very easy. Does not depend on the smaller PCB area for heat dissipation.
