Product Details
Features:
1. Simple step and direction control interface
2. Five different step resolutions: full-step, half-step,
quarter-step, eighth-step, and sixteenth-step
3. Adjustable current control lets you set the maximum current
output with a potentiometer, which lets you use voltages above your
stepper motor’s rated voltage to achieve higher step rates
4. Intelligent chopping control that automatically selects the
correct current decay mode (fast decay or slow decay)
5. Over-temperature thermal shutdown, under-voltage lockout, and
crossover-current protection
6. Short-to-ground and shorted-load protection
7. 4-layer, 2 oz copper PCB for improved heat dissipation
8. Exposed solderable ground pad below the driver IC on the bottom
of the PCB
This product ships with all surface-mount components—including the
A4988 driver IC—installed as shown in the product picture. The
Black Edition has the same component layout and pinout as our A4988
stepper motor driver carrier, so it can be used as a
higher-performance drop-in replacement in applications designed for
our original drivers. The Black Edition achieves its higher
performance through its four-layer printed circuit board (PCB),
which better draws heat out of the A4988 driver—while our original
carrier can deliver up to approximately 1 A per phase in full-step
mode without a heat sink or air flow, the Black Edition can deliver
up to approximately 1.2 A under the same conditions.
