It’s the Circuit Playground Express Base Kit! It provides the few things you’ll need to get started with the new Circuit Playground Express. This version of Circuit Playground is super powered, and will work with Microsoft MakeCode, CircuitPython, code.org CS Discoveries or Arduino IDE.

You can use Circuit Playground Express with code.org CS Discoveries, but we recommend this code.org Individual Pack which has the alligator clips and LEDs you’ll need to follow all the lessons.

Kit includes:

• Circuit Playground Express
• USB cable – A/MicroB – 3ft
• 3 x Alkaline AAA batteries
• 3 x AAA Battery Holder with On/Off Switch, JST, and Belt Clip
• Mini Storage Box

About Circuit Playground Express:

Circuit Playground Express is the next step towards a perfect introduction to electronics and programming. We’ve taken the original Circuit Playground Classic and made it even better! Not only did we pack even more sensors in, we also made it even easier to program. You can now start your journey with Microsoft MakeCode or code.org CS Discoveries. Then, you can use the same board to try CircuitPython, with the Python interpreter running right on the Express. As you progress, you can advance to using Arduino IDE, which has full support of all the hardware down to the low level, so you can make powerful projects.

Because you can program the same board in 3 different ways – the Express has great value and re-usability. From beginners to experts, Circuit Playground Express has something for everyone. If you are looking for our original, Arduino-only Circuit Playground, check out the Circuit Playground Classic.

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

• 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 “#13” LED for basic blinking
• Reset button
• ATSAMD21 ARM Cortex M0 Processor, running at 3.3V and 48MHz
• 2 MB of SPI Flash storage, used primarily with CircuitPython to store code and libraries.
• MicroUSB port for programming and debugging
• USB port can act like serial port, keyboard, mouse, joystick or MIDI!
