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!
