The Circuit Playground Express is Adafruit's flagship educational board designed for CircuitPython. It brings the "batteries included" approach includes an assortment of functionality built-in. It is one of the best beginner boards available. If you are new to hardware, then this is a great board to start with. This version includes 4-H branding approved by the USDA.

Here's some of the great goodies baked in to each Circuit Playground Express:

  • 10 x mini NeoPixels, each one can display any color
  • 1 x Motion sensor (LIS3DH triple-axis accelerometer with tap detection, free-fall detection)
  • 1 x Temperature sensor (thermistor)
  • 1 x Light sensor (phototransistor). Can also act as a color sensor and pulse sensor.
  • 1 x Sound sensor (MEMS microphone)
  • 1 x Mini speaker with class D amplifier (7.5mm magnetic speaker/buzzer)
  • 2 x Push buttons, labeled A and B
  • 1 x Slide switch
  • Infrared receiver and transmitter - can receive and transmit any remote control codes, as well as send messages between Circuit Playground Expresses. Can also act as a proximity sensor.
  • 8 x alligator-clip friendly input/output pins
  • Includes I2C, UART, 8 pins that can do analog inputs, multiple PWM output
  • 7 pads can act as capacitive touch inputs and the 1 remaining is a true analog output
  • Green "ON" LED so you know its powered
  • Red board.D13 LED for basic blinking
  • Reset button
