Maker HAT Base, allows you to easily access the Raspberry Pi 400 GPIO pins

Introduction

It is a bit difficult to access the GPIO pin on the Raspberry Pi 400. By using Maker HAT Base, we can easily make the wiring connections. For this video I will try to do a simple testing, controlling the stepper motor.

Hardware Preparation

This is the list of items used in the video.

• Raspberry Pi 400 Computer Kit
• Maker Hat Base - HAT & GPIO Extension for Raspberry Pi 400
• 3Amp 4V-16V DC Motor Driver (2 Channels)
• NEMA 17HS4401 Bipolar Stepper Motor
• LiPo Rechargeable Battery 3S 11.1V 30C 2200mAH

Sample Program

This is a python sample program to control stepper motor rotation based on 3 styles (single, double and interleave). Please install following libraries:

• CircuitPython for Raspberry Pi (Blinka)
• adafruit-circuitpython-motor library

Thank You
