The Circuit Playground Express is Adafruit's flagship educational board designed for CircuitPython.
It brings the "batteries included" approach includes 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. This version includes 4-H branding [approved by the USDA](https://blog.adafruit.com/2019/03/18/adafruit-circuit-playground-express-4-h-edition-approved-adafruit-4h-4h-4hgrowshere/).

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
* Green "ON" LED so you know its powered
* Red `board.D13` LED for basic blinking
* Reset button
* ATSAMD21 ARM Cortex M0 Processor, running at 3.3V and 48MHz
* 2 MB of SPI Flash storage, used  to store code and libraries.
* MicroUSB port for programming and debugging
* USB port can act like serial port, keyboard, mouse, joystick or MIDI!
* Programmable in multiple environments including Microsoft [MakeCode](https://www.microsoft.com/en-us/makecode), [CircuitPython](https://learn.adafruit.com/welcome-to-circuitpython), [Code.org CSD](https://learn.adafruit.com/adafruit-circuit-playground-express/code-org-csd), and the [Arduino IDE](https://learn.adafruit.com/adafruit-circuit-playground-express/arduino)
