Adafruit Circuit Playground Classic

Would you like to learn electronics, with an all-in-one board that has sensors and LEDs built in? Circuit Playground is here - and it's the best way to practice programming on real hardware with no soldering or sewing required!

This is the Classic version of Circuit Playground, which comes with an ATmega32u4. It's designed to be used with Arduino IDE and code.org CS Discoveries only. It even comes with Firmata already programmed in, so you can use it immediately with code.org Discoveries without any preparation or updates.

If you would like to use MakeCode or CircuitPython, check out Circuit Playground Express, which can be used with MakeCode, CircuitPython or Arduino.

Circuit Playground features an ATmega32u4 processor, just like our popular Flora. The board is also 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). Just program your code into the board then take it on the go!

• ATmega32u4 Processor, running at 3.3V and 8MHz
• MicroUSB port for programming and debugging with Arduino IDE
• USB port can act like serial port, keyboard, mouse, joystick, or MIDI

Built-in USB support allows the board to be programmed simply by plugging it in. All you really need is a Micro-B data/sync USB cable (not included). The Circuit Playground has USB HID support, enabling it to act like a mouse or keyboard.

Features Built-in:

• 10 x mini NeoPixels, each 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)
• 1 x Sound sensor (MEMS microphone)
• 1 x Mini speaker (magnetic buzzer)
• 2 x Push buttons
• 1 x Slide switch
• 8 x alligator-clip friendly input/output pins

Includes I2C, UART, and 4 pins that can do analog inputs/PWM output. All 8 pads can act as capacitive touch inputs.

• Green "ON" LED to show power
• Red "#13" LED for basic blinking
• Reset button
