Stepper Motor HAT (B),Onboard dual HR8825 motor controller IC with built-in microstepping indexer, drives two stepper motors, easy to use. Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano.
6 available microstepping modes. Configured via 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. Protection features: Overcurrent Protection (OCP), Thermal Shutdown (TSD), VM Undervoltage Lockout (UVLO). Integrates 5V regulator, allows providing power to Raspberry Pi. Onboard Different Stepper Motor Interfaces:Easy access to stepper motors in different specifications
