The Circuit Playground Express is Adafruit's flagship educational board designed for CircuitPython.
|
||||
It brings the "batteries included" approach of Python to hardware by including an assortment of
|
||||
functionality built-in. It is one of the best beginner boards available. If you are new to hardware,
|
||||
then this is a great board to start with.
|
||||
|
||||
Here's some of the great goodies baked in to each Circuit Playground Express:
|
||||
|
||||
* 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
