Circuit Playground Expressis the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
Circuit Playground Classicis the original classic Circuit Playground, which is not as powerful or featured. It is designed to be used with Arduino IDE and code.org CS Discoveries only. It does not run MakeCode or CircuitPython, and does not have Infrared support (which is why we made the Express!).
A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
