Please note: This initial run of CPX is for developers and makers only! We're still adding full support for all of the cool sensors to MakeCode/CircuitPython/Arduino. There will be many drastic changes in APIs and functionality, so it is not ready for use with students or beginners: here be dragons!
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. If you are looking for our original, Arduino-only Circuit Playground, check out the Circuit Playground Classic.
The board is round and has alligator-clip pads around it so you don't have to solder or sew to make it work. You can power it from USB, a AAA battery pack, or with a Lipoly battery (for advanced users). Circuit Playground Express has built-in USB support. Built in USB means you plug it in to program it and it just shows up, no special cable or adapter required. Just program your code into the board then take it on the go!
Here's some of the great goodies baked in to each Circuit Playground Express:
