Adafruit nRF52840 Circuit Playground Bluefruit Dev Board

Adafruit nRF52840 Circuit Playground Bluefruit Development Board is the third board in the Circuit Playground series. This breakout board has the nRF52840 microcontroller, which is more powerful and comes with BLUETOOTH® Low Energy support for wireless connectivity. The board is round and has alligator-clip pads, so the user doesn't have to solder to make it work. The user can power it from a USB, an AAA battery pack, or a Lipoly battery (for advanced users). Circuit Playground Bluefruit includes built-in USB support. Built-in USB means it can be plugged in to program it, with no special cable or adapter required. Just program the code into the board and then take it on the go. The user can use this board with Arduino or CircuitPython, but it currently does not support MakeCode.

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 and 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, and multiple PWM outputs
  • Green "ON" LED, so the user knows it is 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
  • The USB port can act like a serial port, keyboard, mouse, joystick, or MIDI
