Circuit Playground Express

Adafruit Circuit Playground Express is an all-in-one design board featuring a processor, sensors, LEDs, USB, and more, making it an ideal introduction to electronics and programming. Circuit Playground Express currently supports programming via Microsoft MakeCode, a web-based code editor for physical computing. Using MakeCode's visual block-based editor, or its JavaScript editor, users can build programs to create custom animations, sounds, and use sensor events like "On Shake" to react to external stimuli. The Circuit Playground Express is based on an ultralow-power SMART SAM L21 Microcontroller, using a 32-bit ARM^® Cortex^®-M0+ core. The SAM L21 features sophisticated power management technologies, allowing for very low current consumption. It can be powered by USB, "AAA" battery pack, or with a Lipoly battery. The round, sensor-packed Circuit Playground Express Board features alligator-clip pads around the edge, making it easy to connect to projects without having to solder. Built-in USB allows quick connectivity for programming, with no special cables or adapters required.
