Bipolar stepper motor driver, 90 to 1500mA , 30V, with microstepping.
The BSD-016 is designed to drive Unipolar and Bipolar Step Motors converting Step and Direction signals from the external microcontroller to amplified phase currents. Any source of TTL level signals (5V logic) can be used as a controlling device for BSD-016 driver.
Once configured correctly the driver does not require any further adjustments or maintenance.
Single voltage supply simplifies power requirements and lowers overall system cost.

This driver features automatic Idle Current Reduction (ICR). If the STEP pulse is missing for longer than 2 seconds, the driver will lower the phase current to the idle value. This idle current may be set from 0 to 100% of the motor current.
The ICR may be enabled or disabled. For example, on the router, you may disable ICR for X and Y drivers, but you may enable it for Z driver.
|Max Current||0 to 1.5A|
