Hi Hasan, You should use the Raspberry Pi to complete the course, because the course was designed for that board. And I can’t guarantee that everything will work with the Orange Pi. But if you only have the Orange Pi you should be able to install Node-RED too and follow along the course.

Hi, thank you my dear what about keypard and mouse for Raspberry Pi  can be using any keypard and mouse or not need that , I am new for using Raspberry Pi  Regards  

You won’t need keyboard or mouse. We’re going to use the SSH communication to talk with the RPi: https://rntlab.com/module-2/connecting-via-ssh-to-your-rpi/
