A4988 Stepper Motor Driver:
● A4988 Stepper Motor Driver Board is a breakout board for Allegro's A4988 DMOS Micro stepping Driver with Translator and Overcurrent Protection
Low RDS (On) Output:
● Automatic current decay mode detection / selection
● Mix with slow current decay modes
● Synchronous rectification for low power dissipation
● Internal UVLO
● Crossover-current protection
● 3.3 and 5 V compatible logic supply
● Thermal shutdown circuitry
● Ground fault protection
● Load short-circuit protection
● Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16
Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble).
Packing List:
● 1 x CNC Shield Board
● 1 x R3 Board for Arduino
● 4 x A4988 Stepper Motor Driver
● 4 x Heat Sink
