Adafruit Circuit Playground Express Developer Edition – Base Kit

Kit includes:

Circuit Playground Express – Developer Edition
USB cable – A/MicroB – 3ft
3 x Alkaline AAA batteries
3 x AAA Battery Holder with On/Off Switch, JST, and Belt Clip
Mini Storage Box

Here’s probably the most great goodies baked in to each and every Circuit Playground:

10 x mini NeoPixels, each and every you could 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). Too can 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 keep an eye on codes, in addition to send messages between Circuit Playground Expresses. Too can act as a proximity sensor.
8 x alligator-clip friendly input/output pins
Includes I2C, UART, 8 pins that may do analog inputs, a couple of PWM output
7 pads can act as capacitive touch inputs and the 1 remaining is a true analog output
Green “ON” LED so you already 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!

Ensure this fits by entering your model number.
