I have attached a parts list for the course. I have provided several options for Raspberry Pi Kits. 

It is probably more cost effective to get a Raspberry Pi kit as it comes bundled with all the components (Power Adapter, SD Card, HDMI cable etc) that you will need to get up and running.  If you buy these items individually, they may be more expensive all together than if you purchased a kit.

Additional components such as the Raspberry Pi Camera Module may be needed if you want to work with and try the hands-on activities with it later on in the course.

A Raspberry Pi 4 is preferred for this course because of the applications that we will be building, but you can also use earlier versions of the Raspberry Pi as well.

I try to keep the online links up to date. So if any of the links are broken, please let me know as soon as possible and I will get them corrected.

Also, if you may be outside the United States and have questions about parts or which Raspberry Pi Kit to purchase based on your local suppliers, please let me know and I will be glad to help.
