Circuit Playground Express is the next step towards a perfect introduction to electronics and programming. We have taken the original Playground Classic Circuit and improved it even further! Not only have we packed even more sensors, but we have also made it even easier to program.

Start your journey with Microsoft MakeCode or Javascript block programming. Then, you can use the same card to try CircuitPython, with the Python interpreter running directly on the Express. As you progress, you can switch to using the Arduino IDE, which supports all hardware down to the lowest level, allowing you to complete powerful projects. code.org CS Discoveries even lets you know everything about coding directly in your browser!

Check out the detailed guide with a guided tour of the Playground Express Circuit and details on how to use MakeCode, CircuitPython, code.org CS Discoveries or Arduino !

Because you can program the same card in 4 different ways - the Express has great value and reusability. From beginner to expert, Circuit Playground Express has something for everyone.

The card is round and surrounded by crocodile clip pads so you don't have to solder or sew to make it work. You can power it from a USB port, an AAA battery or a Lipoly battery (for advanced users). Circuit Playground Express has an integrated USB support. The built-in USB means that you plug it in to program it, no special cables or adapters are required. Just program your code into the card and go!

Here are some of the wonderful features of Circuit Playground Express:

    10 x mini NeoPixels, anyone can display any color
    1 x motion sensor (three-axis LIS3DH accelerometer with tap detection, free fall detection)
    1 x temperature sensor (thermistor)
    1 x Light sensor (phototransistor). Can also be used as a colour and pulse sensor.
    1 x Sound sensor (MEMS microphone)
    1 x Mini loudspeaker with class D amplifier (7.5 mm magnetic loudspeaker/buzzer)
    2 x Push buttons, marked A and B
    1 x Slide switch
    Receiver and Infrared Transmitter - can receive and transmit any remote control code, as well as send messages between Playground Express Circuit. Can also be used as a proximity sensor.
    8 x input/output pins with crocodile clip
    Includes I2C, UART, 8 pins that can make analog inputs, multiple PWM output
    7 pads can be used as capacitive touch inputs and the remaining 1 is a true analog output.
    Green LED "ON" so you know it is on
    Red LED "#13" for basic flashing
    Reset button
    ATSAMD21 ARM Cortex M0 processor, operating at 3.3 V and 48 MHz
    2 MB of SPI Flash storage, used mainly with CircuitPython to store code and libraries.
    MicroUSB port for programming and debugging
    The USB port can act as a serial port, keyboard, mouse, joystick or MIDI!
