Power your precision motion projects with the A4988 Stepper Motor Driver Module. This highly reliable microstepping driver features built-in translator technology, allowing you to control bipolar stepper motors effortlessly using just two pins from your microcontroller: one for steps and one for direction. It comes complete with a clip-on aluminum heatsink to ensure optimal thermal performance during continuous operation.
Widely used in 3D printers (RAMPS setups), CNC shields, and custom robotics automation.
Key Features:
- Adjustable Current Control: Onboard potentiometer allows you to set the maximum current output to match your motor specifications.
- Five Step Resolutions: Supports full-step, half-step, quarter-step, eighth-step, and sixteenth-step microstepping modes.
- Comprehensive Protection: Built-in over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection.
- Intelligent Chopping Control: Automatically selects the correct current decay mode (fast decay or slow decay) for smooth movement.
Technical Specifications:
- Driver IC: Allegro A4988 Microstepping Driver
- Operating Voltage (Logic): 3V - 5.5V DC
- Load Voltage Range (Motor): 8V - 35V DC
- Continuous Current: Up to 1A per phase without a heatsink (up to 2A with the included heatsink and sufficient cooling)
- Interface: Simple STEP and DIRECTION control pins
- Included Accessories: 1x Aluminum heatsink with thermal adhesive backing
