Adafruit 4H Circuit Playground Express Base Kit

Adafruit 4H Circuit Playground Express Base Kit offers all the requirements to start with Circuit Playground Express. The Circuit Playground Express works with Microsoft MakeCode, CircuitPython, CS discoveries, or Arduino IDE. The Circuit Playground Express is an advanced version of the Circuit Playground Classic with more sensors and is easy to program. The base kit comes with 4H Circuit Playground Express, a USB cable (A/MicroB), three alkaline AAA batteries, three AAA battery holders, and a mini storage box.


  • 10x mini NeoPixels, each one can display any color
  • 1x motion sensor (LIS3DH triple-axis accelerometer with tap detection, free-fall detection)
  • 1x temperature sensor (thermistor)
  • 1x light sensor (phototransistor), can also act as a color sensor and pulse sensor
  • 1x sound sensor (MEMS microphone)
  • 1x mini speaker with class D amplifier (7.5mm magnetic speaker/buzzer)
  • 2x pushbuttons, labeled A and B
  • 1x slide switch
  • Infrared receiver/transmitter, can receive and transmit any remote control codes and send messages between Circuit Playground Expresses, can also act as a proximity sensor
  • 8x alligator-clip-friendly input/output pins
  • Includes I2C, UART, 8 pins that can do analog inputs, multiple PWM output
  • 7x pads can act as capacitive touch inputs, and the 1x remaining is a true analog output
  • Green "ON" LED so you know its powered
  • Red "#13" LED for basic blinking
  • Reset button
  • ATSAMD21 ARM Cortex M0 Processor, running at 3.3V and 48MHz
  • 2MB of SPI Flash storage, used primarily with CircuitPython to store code and libraries
  • MicroUSB port for programming and debugging
  • USB port can act like a serial port, keyboard, mouse, joystick, or MIDI
