Adafruit Circuit Playground Express

Key Features:

• Works with Arduino IDE, code.org CS Discoveries, MakeCode & CircuitPython
• ATSAMD21 ARM Cortex M0 Processor (3.3V and 48MHz)
• The original Circuit Playground Classic but even better - more sensors and easier to program
• MicroUSB port for programming and debugging
• USB port can act like serial port, keyboard, mouse, joystick or MIDI

Circuit Playground Express is the next step towards a perfect introduction to electronics and programming. Start your journey with Microsoft MakeCode block-based or Javascript programming. Then, you can use the same board to try CircuitPython, with the Python interpreter running right on the Express. As you progress, you can advance to using Arduino IDE, which has full support of all the hardware down to the low level, so you can make powerful projects.You can even use code.org CS Discoveries to learn all about coding right in your browser! From beginners to experts, Circuit Playground Express has something for everyone. 

The board is round and has 8 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 meaning 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!
