SideStep

Model: SideStep

Stepper Motor Microstepping Driver Specs:

• Chopper Current Driver 0.5 - 2.5 Amp Current Limiting
• Dual H-Bridge Configuration
• Full, Half, Quarter, & Eighth Microstepping ?Buffered Step & Direction Lines
• 8V - 32V Supply

Description:

The SideStep is a complete microstepping motor driver and control system with a built-in translator. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and eighth-step modes, with output drive capability of 32 V and up to 2.5 A. This driver utilizes the Allegro A3977 chip which includes a fixed off-time current regulator that has the ability to operate in slow-, fast-, or mixed-decay modes. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation. The SideStep is one of the smallest stepper driver boards in its class, making it ideal for incorporating into robots and other industrial control equipment.

Features:

• Hardware or software selectable step and direction signals
• Current limit adjustable by potentiometer
• Wide range of motor power (5-35 V)
• Power (for logic) indicator LED
• 2.5 A, 35 V Output Rating
• Automatic Current Decay Mode Detection/Selection Mixed-, Fast-, and Slo- Decay Modes
• 3.0-5.5 V Logic Supply Voltage Range
• Synchronous Rectification for Low Power Dissipation
• Internal UVLO and Thermal-Shutdown Circuitry
• Crossover Current Protection
