he A4988 micro-stepping stepper motor driver is a Pololu format compatible driver, ideal for Shield and breadboard compatibility. The A4988 at 2 amps capable and 35 volts of drive capacity makes this a perfect match for 3D printer all-in-one boards, such as “RAMPS” with plug and play compatibility.
The micro stepper driver supports full, half, ¼, 1/8 and 1/16 step modes for bipolar stepper motors. The A4988 driver also supports automatic current decay, reducing motor noise, heat, and power consumption while increasing step accuracy.
Features:
• Low RDS output
• Automatic current decay mode detection
• Mix and slow current decay modes
• Synchronous rectification for low power dissipation
• Internal UVLO
• Cross-current protection
• 3.3v and 5v compatible logic supply
• Thermal shutdown circuitry
• Ground fault protection
• Load short-circuit protection
• Full, half, ¼, 1/8, 1/16 step modes
Specs:
Drive voltage: 5-35v
Logic voltage: 3.3-5v
Format: 16pin “Pololu format”
Drive amps: 2A
