Why we LOVE this product!
This is where SparkBlocks moves from wiring lights to real electronics. Transistors and capacitors are what make everyday devices work, and here kids can see them in action inside brick-built machines.
The remote-controlled builds give older kids a reason to keep going.
Two things to weigh: it's expensive, and it isn't a starting point, so it only makes sense after the Intro Kit.
Description
SKU:
BC2001
The SparkBlocks Expansion Kit adds more advanced electronic blocks to the Intro to Circuits Kit, including resistors, capacitors, transistors, two geared motors and a remote control, with four new builds and experiments in circuit logic and sensors.
What's inside
- USB-C power block and charging cable
- 2 high-torque geared motors
- 4 LED blocks
- Remote control block and remote
- 8 resistors and 8 capacitors
- 4 transistors (2 NPN, 2 PNP)
- Slide switch, push button and light sensor
- Crossover connectors, wire blocks, stud-to-wire blocks and jumper wires
- 200+ building bricks
- Instructions, and a plastic case with a labeled foam insert
How it works
Kids build four advanced projects, a parade float, a night-light castle, a dual conveyor system and a clean-up bot, and work through experiments with real components such as transistors and capacitors.
What kids learn
- Electronics: what resistors, capacitors and transistors do
- Circuit logic: building circuits that make decisions
- Sensors and signals: light sensing and remote control
- Engineering: machines with two motors
Good to know before you buy
- Needs the Intro to Circuits Kit (or the SparkBlocks Advanced Set, which includes both).
- Age: SparkBlocks designs it for ages 8 and up; the content suits kids who have finished the Intro Kit.
- Price: $279.00 at SparkBlocks at the time of writing (US dollars for US visitors).
Who it's for
Kids who have outgrown the Intro Kit and want to understand how real electronics work, and homeschool families looking for a longer electronics unit.

About
SparkBlocks
SparkBlocks was created by two parents who wanted to make STEM learning more hands-on, accessible, and fun. The idea began in 2021, when founder Mark started exploring how electronic components could be built directly into familiar construction bricks. After years of experimenting with circuits, connections, and designs, he developed a system that lets children bring their building creations to life with real electronics. Co-founder Holden joined in 2024 to help refine the system and bring it to more families.
SparkBlocks combines the creativity of construction play with the excitement of discovering how technology works. Its electronic building blocks connect with LEGO®-compatible bricks and can be used to create projects featuring lights, motors, switches, sensors, and sound. Children can follow visual instructions to build working models, then experiment with their own ideas, learning about circuits, engineering, and problem-solving along the way.
Designed for screen-free play, SparkBlocks encourages children to build, test, troubleshoot, and try again. The reusable components can be rearranged into new creations, allowing the possibilities to grow as a child's confidence and skills develop. By making real electronics tangible and playful, SparkBlocks helps young builders move beyond following instructions to understanding how things work and inventing something of their own.
