Expansion Kit

More components. More experiments. More ways to learn.

Already have the Intro Kit?  This Expansion Kit builds on it with additional electronic components and new hands-on projects designed for curious kids and families. It’s ideal for families, educators, and young builders ages 8+ who want to explore electronics through guided, creative play.

This kit introduces new click-together electronic blocks including resistors, capacitors, transistors, sensors, and switches. All components are designed for safe, hands-on learning and work seamlessly with SparkBlocks and standard building bricks.

Kids (and kids at heart!) can build moving models, light-up creations, and interactive projects while learning real electronics concepts like circuits, signals, and sensors in a clear, age-appropriate way. Build remote-controlled machines, experiment with real logic circuits, and explore how real-world electronics come to life through hands-on play.

  • Parade Float
  • Night Light Castle (yes, it really works!)
  • Dual Conveyor System
  • Clean Up Bot
• 🎮 Add 2 gearbox motors + remote control + tons more!

Important note

The Expansion Kit is designed to build on the basics. To get started, you’ll need either the Intro to Circuits Kit (for battery power and core circuit blocks) or the Advanced Set, which includes both.
