TB67S109 Stepper Motor Driver Board

This stepper motor driver is based on the Toshiba TB67S109 stepper motor driver chip design. It uses four layers of thick copper precipitation PCB with automatic patch processing. This driver uses the indexer (DIR / STEP) control interface. The maximum drive current can reach 4A. Can use 57 stepper motors compatible with Pololu pin definition.
