Dnub-at1-236b- Driver May 2026

Before integrating the Dnub-at1-236b- Driver into any system, understanding its electrical limits is critical for avoiding cascade failures.

| Parameter | Value | Tolerance | | :--- | :--- | :--- | | Input Voltage (VM) | 12V – 36V DC | ±5% | | Output Current (Peak) | 2.36 A (Adjustable via potentiometer) | ±2% | | Logic Voltage (VCC) | 3.3V – 5V DC | ±10% | | Microstep Resolution | Full, 1/2, 1/4, 1/8, 1/16 | Programmable | | PWM Switching Frequency | 28 kHz (Silent operation band) | Fixed | | Operating Temperature | -20°C to +85°C | Derated above 70°C | | Protection Features | Over-current, short-circuit, thermal shutdown | Auto-reset | Dnub-at1-236b- Driver

  • Interrupt handling:
  • Configuration interface:
  • Power management:

    • Prerequisites: Multimeter, soldering iron (if using bare PCB), heat sink, thermal paste. Interrupt handling:

  • Wiring the Motor: Identify the coil pairs on your stepper motor using a continuity test. Connect one pair to A1/A2 and the other to B1/B2. Reversing a pair will reverse the motor direction.
  • Logic Connection: Interface the STEP and DIR pins to your microcontroller. For Arduino users, a simple digitalWrite(StepPin, HIGH) followed by a delayMicroseconds(5) is sufficient to trigger the driver.
