This module is designed to drive bipolar stepper motors in full, half, quarter, eighth, and sixteenth-step modes. It is commonly utilized in 3D printers, CNC machines, and other automated motion control systems requiring precise motor positioning.\u003c\/p\u003e\u003ch2\u003eKey Technical Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIntegrated translator for simple step and direction control.\u003c\/li\u003e\n\u003cli\u003eFive selectable step resolutions: full, 1\/2, 1\/4, 1\/8, and 1\/16.\u003c\/li\u003e\n\u003cli\u003eAdjustable current control via onboard potentiometer to set maximum current output.\u003c\/li\u003e\n\u003cli\u003eIntelligent chopping control that automatically selects the correct current decay mode.\u003c\/li\u003e\n\u003cli\u003eThermal shutdown circuitry, under-voltage lockout, and crossover-current protection.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ch2\u003e ParameterSpecification Controller ICA4988 Operating Voltage8V to 35V Logic Voltage3.3V to 5V Max Current1A per phase (without cooling), up to 2A with adequate heat sinking Microstep Resolutions1, 1\/2, 1\/4, 1\/8, 1\/16 Dimensions20mm x 15mm Kit Package Contents\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e5x A4988 Stepper Motor Driver Modules (Red PCB)\u003c\/li\u003e\n\u003cli\u003e5x Aluminum Heat Sinks with adhesive backing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePinout \u0026amp; Interface Usage Notes\u003c\/h2\u003e\u003cp\u003eThe module interfaces via standard STEP and DIR pins for motion control. The MS1, MS2, and MS3 pins are used to configure the microstepping resolution. The ENABLE pin allows for disabling the driver outputs. Users must adjust the onboard potentiometer to limit the current supplied to the motor coils to prevent overheating. It is recommended to monitor the Vref voltage during adjustment to ensure the current does not exceed the motor's rated specifications. Always ensure power is disconnected before adjusting the potentiometer or connecting\/disconnecting motors to prevent damage to the driver IC.\u003c\/p\u003e","brand":"Generic","offers":[{"title":"Default Title","offer_id":43934969266289,"sku":null,"price":19.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0073\/8344\/9713\/files\/NewProject.jpg?v=1786412958","url":"https:\/\/3dprintingperth.com\/products\/a4988-stepper-motor-driver-module-with-heat-sink-5-pack-kit","provider":"3D Printing Perth - Cirrus Link","version":"1.0","type":"link"}
