Circuit Playground Express is the next step towards a perfect introduction to electronics and programming. We’ve taken the original Circuit Playground Classic and made it even better! Not only did we pack even more sensors in, we also made it even easier to program.
Because you can program the same board in 3 different ways – the Express has great value and re-usability. From beginners to experts, Circuit Playground Express has something for everyone.
