The CPX packs a ton of parts into a very small package. These include an accelerometer, temperature sensor, light sensor, microphone, miniature speaker, infrared receiver and transmitter, 3 buttons, 1 slide switch, 7 capacitive touch pads, and 10 individually addressable RGB neopixels all running on an ATSAMD21 ARM Cortx M0 professor with 2MB of onboard SPI Flash storage.
All of this combined with Arduino, CircuitPython, and MakeCode compatibility make the Circuit Playground Express one of the most agile and accessible boards to teach programming skills.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
