USB Serial Communication Using Raspberry Pi and Microbit

Introduction

To expand controller capability, sometimes it is necessary to communicate with other controllers. There have few common protocols in controller communication e.g. UART, I2C, SPI and etc. This tutorial will share on how to do the UART serial communication between Raspberry Pi and micro:bit through USB connection.

Video

This video shows how to do serial communication between Raspberry Pi and micro:bit over a USB connection.

Hardware Preparation

This is the list of items used in the video.

• Raspberry Pi 4 Model B (2GB)
