Description

HUAREW A4988 Stepstick Motor Driver Module with Heat Sink Applications: Widely used in Stepper motors, 3D printer, small CNC machines, engraving machines, Supported 3d printers like Prusa Mendel, ultimaker, printbot and so on Specifications: Chip:A4988 Color:red The drive current: 2A (best to install the heat sink) Step mode: full, 1/2, 1/4, 1/8 and 1/16 Feature: Thermal shutdown circuit Ground short circuit protection Load short-circuit protection crossover current protection 3.3 and 5 V compatible logic supply Mixed with slow current decay modes Synchronous rectification for low power dissipation Automatic current decay mode detection/selection Adjustable current control lets you set the maximum current output with a potentiometer The A4988 interface is ideal for applications where complex microprocessors are unavailable or overloaded The A4988 comes in a surface-mounted QFN package (ES) with an exposed cooling panel for enhanced heat dissipation Package Included: 5 piece A4988 Stepstick Motor Driver Module 5 piece Heatsink

Features

• A4988 is a complete micro-stepping motor driver with a built-in converter, easy to operate
• A4988 can operate dual stepper motors in full, half, 1/4, 1/8, and 1/16 stepper modes, Output drive capacity of up to 35 V and ± 1A
• Protection function, the stepper motor drive modules can provide Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
• Intelligent chopping control, Chopping control within A4988 can automatically select the current decay mode(fast decay or slow decay)
• As long as a pulse is input into the "Step" input, the motor can be driven to generate micro steps. No phase sequence table, high frequency control line or complex interface programming is required
