Circuit Playground Express Developer
Edition - Base Kit
PRODUCT ID: 3517
Description
Please note: This initial run of CPX is for developers and makers only! We're still adding full
support for all of the cool sensors to MakeCode/CircuitPython/Arduino. There will be many drastic
changes in APIs and functionality, so it is not ready for use with students or beginners: here be
dragons!
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 or Arduino IDE. If you are looking for our original, Arduino-only
Circuit Playground, check out the Circuit Playground Classic.
Kit includes:
o Circuit Playground Express - Developer Edition
o USB cable - A/MicroB - 3ft
o 3 x Alkaline AAA batteries
o 3 x AAA Battery Holder with On/Off Switch, JST, and Belt Clip
o 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 block-based or Javascript programming. 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:
o 10 x mini NeoPixels, each one can display any color
o 1 x Motion sensor (LIS3DH triple-axis accelerometer with tap detection, free-fall detection)
o 1 x Temperature sensor (thermistor)
o 1 x Light sensor (phototransistor). Can also act as a color sensor and pulse sensor.
o 1 x Sound sensor (MEMS microphone)
o 1 x Mini speaker with class D amplifier (7.5mm magnetic speaker/buzzer)
o 2 x Push buttons, labeled A and B
o 1 x Slide switch
o 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.
o 8 x alligator-clip friendly input/output pins
o Includes I2C, UART, 8 pins that can do analog inputs, multiple PWM output
o 7 pads can act as capacitive touch inputs and the 1 remaining is a true analog output
o Green "ON" LED so you know its powered
o Red "#13" LED for basic blinking
o Reset button
o ATSAMD21 ARM Cortex M0 Processor, running at 3.3V and 48MHz
o 2 MB of SPI Flash storage, used primarily with CircuitPython to store code and libraries.
o MicroUSB port for programming and debugging
o USB port can act like serial port, keyboard, mouse, joystick or MIDI!
Technical Details
o Circuit Playground outer diameter: ~50.6mm / ~2.0"
o Circuit Playground weight: 8.5g
