Arduino Pro Mini 5V 16MHz

Key Features :

• • • Model:DRV8825
    • Supply Voltage:8.2 42 VDC.
    • Current Capacity :2.2A max(24V).
    • Continuous current per phase:1.5 A.
    • Minimum Logic voltage:2.5V.
    • Maximum Logic Voltage:5V.
    • Microstep resolutions:full, 1/2, 1/4, 1/8, 1/16, and 1/32.
    • Dimensions: 15 x 20 mm.
    • Weight:4 gm.
    • Microstep resolutions:full, 1/2, 1/4, 1/8, 1/16, and 1/32.
    • Simple step and direction control interface
    • Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
    • Adjustable current control lets you set the maximum current output with a potentiometer. Hence lets you use voltages above your stepper motors rated voltage to achieve higher step rates
    • Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
    • 45V maximum supply voltage
    • Built-in regulator (no external logic voltage supply needed)
    • Can interface directly with 3.3V and 5V systems
    • Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
    • Short-to-ground and shorted-load protection
    • 4-layer, 2oz copper PCB for improved heat dissipation
    • Exposed solderable ground pad below the driver IC on the bottom of the PCB
