This Stepper Motor HAT gives your Raspberry Pi the ability to drive two stepper motors at the same time and supports up to 1/32 microstepping. This version uses aDRV8825 controller. The HAT features six step modes (full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step) and includes multiple connector options to accommodate a range of stepper motors. An onboard 5V regulator has been included to power your Raspberry Pi. Note: Stepper motors NOT included Features Standard Raspberry Pi 40-pin GPIO extension header Onboard dual DRV8825 motor controller IC with built-in microstepping indexer Drives two stepper motors 6 available microstepping modes, configured with the DIP switches: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step Adjustable motor drive current via potentiometer, maximum 2.5A current output Overcurrent Protection (OCP) Thermal Shutdown (TSD) VM Undervoltage Lockout (UVLO) Integrates 5V regulator providing power to your Raspberry Pi Onboard multi-connector options for stepper motors in different specifications Comes with development resources and manual 2.1/5.5mm barrel jack connection Resources Product Wiki User manual Libraries Specifications Motor controller: DRV8825 Motor drive voltage: 8.2V~28V Motor drive current: 2.5A Logic voltage: 3.3V Dimension: 65mm 56mm Mounting hole size: 3.0mm Applications 3D Printer Sculpturing machine Mechanical arm
