{"title":"Circuit Playground Bluefruit Bluetooth LE Board","handle":"circuit-playground-bluefruit-bluetooth-lowenergy-gh-studen","url":"/products/circuit-playground-bluefruit-bluetooth-lowenergy-gh-studen","description":"Circuit Playground Bluefruit is a round, beginner-friendly electronics and programming board with Bluetooth® Low Energy built in. It builds on the Circuit Playground Express concept with a more powerful nRF52840 microcontroller, making it suitable for wireless projects, wearables, sensors, interactive art and learning to code.The board has large alligator-clip friendly pads around the edge, so you can connect components without soldering or sewing. It can be powered from USB, a AAA battery pack, or a LiPo battery for more advanced portable projects.Built-in USB support means you can plug it in directly for programming and debugging with no special cable or adaptor required. It can be used with Arduino or CircuitPython; MakeCode is not supported at this time.Features:Processor: 1 x nRF52840 Cortex M4 processor with Bluetooth® Low Energy supportNeoPixels: 10 x mini NeoPixelsNeoPixel colour: Each mini NeoPixel can display any colourMotion sensor: 1 x LIS3DH triple-axis accelerometerTap detection: Supported by the LIS3DH motion sensorFree-fall detection: Supported by the LIS3DH motion sensorTemperature sensor: 1 x thermistorLight sensor: 1 x phototransistorColour sensor capability: The light sensor can also act as a colour sensorPulse sensor capability: The light sensor can also act as a pulse sensorSound sensor: 1 x MEMS microphoneSpeaker: 1 x mini speaker with class D amplifierSpeaker size/type: 7.5mm magnetic speaker/buzzerPush buttons: 2 x push buttons, labelled A and BSlide switch: 1 x slide switchI/O pads: 8 x alligator-clip friendly input/output pinsI2C: IncludedUART: IncludedAnalogue inputs: 6 pins can do analogue inputsPWM outputs: Multiple PWM outputsPower LED: Green “ON” LED so you know it is poweredBlink LED: Red “#13” LED for basic blinkingReset: Reset buttonFlash storage: 2 MB of SPI Flash storage, used primarily with CircuitPython to store code and librariesUSB connector: MicroUSB port for programming and debuggingUSB serial: USB port can act like a serial portUSB keyboard: USB port can act like a keyboardUSB mouse: USB port can act like a mouseUSB joystick: USB port can act like a joystickUSB MIDI: USB port can act like MIDILow-power control: A pin allows the user to turn off power to the NeoPixels, microphone, and temperature/light sensor so only the accelerometer is active, for low power usageSpecifications:Outer Diameter: ~50.6mm / ~2.0\"Weight: 8.9gA great choice for learning CircuitPython or Arduino with built-in sensors, LEDs, sound, Bluetooth LE and clip-friendly connections in one compact board.","vendor":"Adafruit","product_type":"Microcontroller Board","in_stock":true,"options":[],"variants":[{"id":16346,"title":"Default Title","sku":"AF-764","mpn":"ADA764","price":61.35,"on_sale":false,"in_stock":true,"available_quantity":41}]}
