Interface Signal
| Name | Function |
| PUL | Pulse signal: rising edge is valid, the motor step when pulse is from low to high. |
| DIR | Direction signal: can change motor direction, TTL level drive. |
| OPTO | Optical coupling drive power supply |
| ENA | Enable signal: forbid or enable drive to work, low level is forbid. |
| GND | DC power ground |
| +V | DC power positive pole, +18V-+40V any value is OK, recommend value is +24V. |
| A+ | Motor A phase |
| A- | Motor A phase |
| B+ | Motor B phase |
| B- | Motor B phase |
