3-channel motor driver board_2023-11-11

Overview

This project uses the DRV8825PWP main control chip and CD4069 chip to create a stepper motor drive circuit. The project consists of two parts: a power supply circuit and a motor drive circuit. The power supply circuit mainly uses 12V and 3.3V power supplies. The
motor drive first transmits the externally sent signal to the CD4069 inverter through terminal connections, then transmits it to the three control pins of the DRV8825PWP chip, ultimately controlling the stepper motor. The project design is simple and can be used for electronic design courses. After completion, it can also be applied to learning. Based on this, it can be expanded to control other types of motors. (
Schematic design,

PCB design,

3D rendering, and

physical prototype are included.)
