Makeblock MegaPi Pro DRV8825 Stepper Motor Driver 4 Layer with Mini Heat Sink for 3D Printer

Description: This module is designed to drive stepper motors. It uses the DRV8825 chip and has a maximum driving current of 2.5 A. DRV8825 is a complete micro-stepping motor driver, equipped with a built-in converter for easy operation. It is designed to drive bipolar stepper motors that work in full, 1/2, 1/4, 1/8/ 1/16, or 1/32 step modes. An on-board potentiometer is provided, which allows you to change the current of a motor easily. Features: Compatible with 4-wire bipolar stepper motors Potentiometer, used to control the current of a stepper motor On-board heat sink, facilitating heat dissipation Capable of driving one-step stepper motors (green interface) Color-coded male and female pins, ensuring correct connection Small size, facilitating connection Specifications: Motor driver: DRV8825 Output current?1.75 A (with proper heat sinking at 24 V and 25°C) Max current: 2.5 A (pay attention to heat dissipation) Driver voltage: 8.2 V–45 V Note: The maximum power supply voltage of MegaPi is 12 V. Logic voltage: 5 V Dimensions: 1.5 cm x 2.0 cm" Coding Demo: Arduino IDE: https://github.com/Brandonwong11/makeblock-MegaPiPro/tree/master/examples/Arduino/42BYG_Stepper_Motor mBlock3 & Makeblock Graphical Programming: https://github.com/Brandonwong11/makeblock-MegaPiPro/blob/master/examples/mBlock3/42BYG%20Stepper%20Motor.sb2 https://github.com/Brandonwong11/makeblock-MegaPiPro/blob/master/examples/mBlock5/42BYG%20Stepper%20Motor.mblock Raspberry Pi Python3: https://github.com/Brandonwong11/makeblock-MegaPiPro/blob/master/examples/Python3/StepperMotor_1.py https://github.com/Brandonwong11/makeblock-MegaPiPro/blob/master/examples/Python3/StepperMotor_2.py
