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.

    Great toy for creativity and introduction into electricity and circuitry.

    I got the basic kit, the expansion pack and the walking ant model. My little one is only 3.5 years old so she’s not really getting the electrical circuitry thing just yet but it is a very visual way to teach her that when things are connected up to a source of power, they can give out lights/sound/movement etc. She’s having a great time just putting the LED block on the battery pack then taking it off in an infinite loop. I think it’s me that’s getting the most out of these kits atm but I’m sure my little one will grow into this.

    The circuitry concept did take some time for me to understand (coming from a non-tech background) but I’m getting there. The block quality are good. Not excellent but very decently made and they fit together absolutely fine. One outstanding aspect is the company’s customer service! The battery and motor in my set arrived slightly defective, the company was extremely fast to respond and arrange for replacements. I was very very impressed.

    Really thoughtful review, thank you Watoo. And yes, for younger builders, even simple cause-and-effect moments like turning on a light can be magical learning. Also appreciate the kind words about support, we know early production runs aren’t perfect and we work hard to make things right quickly when issues pop up. (And make sure to check the updated build pictures for the night light for the Expansion Kit! It's on SparkBlocks.ca/info ) Keep building!

    Fantastic!

    My 9 year old loves it! He started off following the instructions and quickly moved to making his own creations. His favorite so far was making a vehicle that moves :) It's been a great way to take his interest in Minestone circuits and translate that into something more hands-on that he loves just as much. Money well spent!

    This is fantastic to hear. Going from following instructions to inventing original moving creations is exactly the progression we hope for. Also love the Minecraft-to-real-circuits connection, that’s such a cool bridge into hands-on STEM learning. ⚡

    Takes STEM learning to the next level with even more hands-on builds

    SparkBlocks Expansion Kit has been a great addition to the original set. It adds more advanced components and builds that keep kids engaged while introducing real circuit concepts in a hands-on, easy-to-understand way. My child loved being able to create moving and light-up projects, and I appreciated how it builds on what they already learned without feeling overwhelming. It’s a fun, screen-free way to take STEM learning to the next level.

    Great addition to Intro Kit

    For kids who like to build big, the expansion pack is key. It adds an additional power option, more parts and fun add-ons. By having the intro kit and expansion kit, the possibilities for builds increase exponentially.

    Thanks, Carrie! Totally - the gearbox motor isn't in the Intro kit and opens up TONS of new build possibilities! ‘Build big’ is the perfect way to put it 👍
