Product Description: The SureStepr SD6128 is a THB6128 chip-based stepper driver board. It is designed for simplicity in operation, using an indexer (DIR/STEP) interface to manage the movement of stepper motors. This product serves as an effective replacement for Pololu style footprint drivers like the SD8825, A4988, A4983, and Stepsticks. One unique attribute of the SD6128 is its heat pad located on the top of the chip, facilitating more efficient heat sinking that does not depend on the small PCB area for heat dissipation.
Key Features:
- Manufactured with a 4 Layer RoHS PCB
- Supports microstepping fractals: 1, ½ , ¼, ⅛, 1/16, 1/32, 1/64, and 1/128
- Peak drive current capped at 2.2A
- Heat pad is mounted on the top
- Larger area for mounting the heat sink
- Easy-to-use DIR/Step interface
- Output pins support Decay and external Vref
- The driver chip, THB6128, has overcurrent and over-temperature protection
- The maximum motor supply current is 2.2A
- Maximum motor voltage is 35V
