Adafruit's Circuit Playground Bluefruit
Third gen version of Adafruit's popular circular MCU
Description
- The main chip is an nRF52840, with Bluetooth Low Energy
- Outer Diameter: ~50.6mm / ~2.0"
- Weight: 8.9g
Features
- 1 x nRF52840 Cortex M4 processor with Bluetooth Low Energy support
- 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
- 8 x alligator-clip friendly input/output pins
- Includes I2C, UART, 6 pins that can do analog inputs, multiple PWM outputs
- Green "ON" LED so you know its powered
- Red "#13" LED for basic blinking
- Reset button
- 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

Arduino IDE
MicroPython
- Adafruit no longer supports MicroPython on its boards. Use CircuitPython for official support.
-
- MicroPython is a complete re-write of the Python (version 3.4) programming language so that it fits and runs on a microcontroller. It includes many optimizations so that it runs efficiently and uses very little RAM.
