3000: Circuit Playground Classic - ATmega32U4

Circuit Playground features an ATmega32u4 micro-processor, just like our popular Flora. It also is round and has alligator-clip pads around it. You can power it from USB, a AAA battery pack, or Lipoly (for advanced users). Program your code into it, then take it on the go.Circuit Playground features an ATmega32u4 micro-processor, just like our popular Flora. It also is round and has alligator-clip pads around it.

Circuit Playground has built-in USB support. Built in USB means you plug it in to program it, it just shows up - all you need is a Micro-B USB cable. With the new 1.6.4+ Arduino IDE, it takes only a few seconds to add support. The Circuit Playground has USB HID support, so it can act like a mouse or keyboard to attach directly to computers.

Here's some of the great goodies baked in:

• 10 x mini NeoPixels, each one can display any rainbow 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, left and right

• 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 so you know its powered

• Red "#13" LED for basic blinking

• Reset button

• 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
