Stepper Motor HAT for Raspberry Pi

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 a DRV8825 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
