128 Microstep SD6128 V1.1 Stepstick Stepper Motor Driver Module with Heatsink for 3D Printer,Default NO5246

Description:

The SureStepr SD6128 is a stepper driver board based on the THB6128 chip. It is simple to use and operate using an indexer (DIR/STEP) interface to move the stepper motors. The SD6128 is a drop-in replacement for Pololu style footprint drivers including the SD8825, A4988, A4983 and Stepsticks. One distinct feature of the SD6128 is that heat pad is located at the top of the chip. This makes heat sinking a lot easier and does not rely on the already small PCB area for heat dissipation.

Feature:

Made with 4 Layer RoHS PCB

1, 1/2 , 1/4, 1/16, 1/32, 1/64 and 1/128 Microstepping
