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. If you're in a classroom following Code.org's CS Discoveries curriculum, you can use the Express by updating the firmware. 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.

The board is round and has alligator-clip pads around it so you don't have to solder or sew to make it work. You can power it from USB, a AAA battery pack, or with a Lipoly battery (for advanced users). Circuit Playground Express has built-in USB support. Built in USB means you plug it in to program it and it just shows up, no special cable or adapter required. Just program your code into the board then take it on the go!

Pack includes:

• 2 x Circuit Playground Express

• 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!
