KNOWLEDGE and EXPERIENCE are what is needed to succeed and that is what you get with these Mr Circuit STEM KITS.

You get knowledge of electronics principles and hands-on experience assembling and troubleshooting electronic circuits while reading schematics and handling electronic components.

You are helped by step by step instructions, video presentations, online practice quizzes, and free tech support online and by phone with a live person. You will be amazed at how much you will learn by completing each Mr Circuit STEM KIT.

The Mr Circuit STEM KITS are reusable so multiple students can use them.  Each one comes with an Alkaline 9-Volt Battery and a 400-connection Solderless Circuit Board.  Each STEM KIT is available for easy replacement as they wear out.

Order today and get started having fun and growing in knowledge of electronics technology!
