Why choose the SIK?

The SparkFun Inventor's Kit is a great way to get started with programming and hardware interaction with the Arduino programming language.

Project-Based Learning

The SIK is organized around five projects that progress in difficulty, building on the skills learned in each of 16 circuits. Create games, robots, alarms, sensors and more while learning basic concepts of electricity and programming.

More Than Just Materials

The spiral-bound SIK guidebook is your manual to learn electronics. Each circuit is easy to follow complete with detailed instruction and imagery. The guidebook also dives deeper into concepts and provides coding challenges along the way.

Easily Expand with Qwiic Connect System

This latest version of the SIK (4.1) includes the Redboard Qwiic which allows you to expand into the SparkFun Qwiic ecosystem (I2C sensors, actuators, shields and cables) after you have become proficient with the SIK circuits in the guidebook.

    My parents kindly purchased me one of these when I was in seventh grade, and now I have a degree in computer engineering and work in the industry. Still have it in a parts drawer. Much love for the SIK.

    • That is so awesome to hear! That's what was hoped for, use in the inspiration in electronics, in all the iterations of the SIK over the years.
