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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
