A4988 Stepper motor driver, with heat sink

The A4988 is a complete micro stepping motor driver with built-in translator for easy operation.

This A4988 can ru your stepper motor in full, half, 1/4, 1/8 and 1/16 step modes, output drive capacity of up to 35 V and ± 2 A.

A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes.

Comes with heat sink.

Features and Benefits:

• Low RDS (On) Output
• Automatic current decay mode detection / selection
• Mix with slow current decay modes
• Synchronous rectification for low power dissipation
• Cross-current protection
• 3.3 and 5 V compatible logic supply
• Thermal shutdown circuitry
• Ground fault protection
• Load short-circuit protection
• Optional step modes: full, 1/2, 1/4, 1/8 and 1/16
