We've taken the popular Circuit Playground Express and made it even better! Now the main chip is an nRF52840 microcontroller which is not only more powerful, but also comes with Bluetooth Low Energy support for wireless connectivity.The board is round and has alligator-clip pads around it so you don't have to solder or sew to make it work. You can power it from USB, a AAA battery pack, or with a Lipoly battery (for advanced users). Circuit Playground Bluefruit has built-in USB support. Built in USB means you plug it in to program it and it just shows up, no special cable or adapter required. Just program your code into the board then take it on the go!You can use this board with Arduino or CircuitPython - It does not support MakeCode at this time (there is no ETA when it might be added)Here's some of the great goodies baked in to each Circuit Playground Bluefruit:1 x nRF52840 Cortex M4 processor with Bluetooth Low Energy support10 x mini NeoPixels, each one can display any color1 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 B1 x Slide switch8 x alligator-clip friendly input\/output pinsIncludes I2C, UART, 6 pins that can do analog inputs, multiple PWM outputsGreen "ON" LED so you know its poweredRed "#13" LED for basic blinkingReset button2 MB of SPI Flash storage, used primarily with CircuitPython to store code and libraries.MicroUSB port for programming and debuggingUSB port can act like serial port, keyboard, mouse, joystick or MIDI!"}}</script> <div class="row product-info"> <div class="mobile-product-header"> <h1 class="product-name-large">Circuit Playground Bluefruit - Bluetooth Low Energy</h1> <div

We've taken the popular Circuit Playground Express and made it even better! Now the main chip is an nRF52840 microcontroller which is not only more powerful, but also comes with Bluetooth Low Energy support for wireless connectivity.</p><ul></ul><p>The board is round and has alligator-clip pads around it so you don't have to solder or sew to make it work. You can power it from USB, <a href="https://www.adafruit.com/products/727">a AAA battery pack</a>, or with a Lipoly battery (for advanced users). Circuit Playground Bluefruit has built-in USB support. Built in USB means you plug it in to program it and it just shows up, no special cable or adapter required. Just program your code into the board then take it on the go!</p><p>You can use this board with <strong>Arduino</strong> or <strong>CircuitPython</strong> - It does not support MakeCode at this time (there is no ETA when it might be added)</p><p>Here's some of the great goodies baked in to each Circuit Playground Bluefruit:</p><ul><li>1 x nRF52840 Cortex M4 processor with Bluetooth Low Energy support</li><li>10 x mini NeoPixels, each one can display any color</li><li>1 x Motion sensor (LIS3DH triple-axis accelerometer with tap detection, free-fall detection)</li><li>1 x Temperature sensor (thermistor)</li><li>1 x Light sensor (phototransistor). Can also act as a color sensor and pulse sensor.</li><li>1 x Sound sensor (MEMS microphone)</li><li>1 x Mini speaker with class D amplifier (7.5mm magnetic speaker/buzzer)</li><li>2 x Push buttons, labeled A and B</li><li>1 x Slide switch</li><li>8 x alligator-clip friendly input/output pins</li><li>Includes I2C, UART, 6 pins that can do analog inputs, multiple PWM outputs</li><li>Green "ON" LED so you know its powered</li><li>Red "#13" LED for basic blinking</li><li>Reset button</li><li>2 MB of SPI Flash storage, used primarily with CircuitPython to store code and libraries.</li><li>MicroUSB port for programming and debugging</li><li>USB port can act like serial port, keyboard, mouse, joystick or MIDI!</li></ul><p><lite-youtube videoid="4lGRgO40UhM" title="Circuit Playground is for everyone @adafruit #adafruit" style="background-image: url(https://cdn-shop.adafruit.com/ytimg/vi/4lGRgO40UhM/hqdefault.jpg)" params="" > <a href="https://www.youtube.com/watch?v=4lGRgO40UhM" class="lyt-playbtn" title="Play video"> <span class="lyt-visually-hidden">Play video: Circuit Playground is for everyone @adafruit #adafruit</span> </a> </lite-youtube></p><p><lite-youtube videoid="iKjpS5VYQ4A" title="New Products 11/27/2019 Featuring LPS33HW Water Resistant Pressure Sensor @adafruit #adafruit" style="background-image: url(https://cdn-shop.adafruit.com/ytimg/vi/iKjpS5VYQ4A/hqdefault.jpg)" params="start=320" > <a href="https://www.youtube.com/watch?v=iKjpS5VYQ4A&t=320" class="lyt-playbtn" title="Play video"> <span class="lyt-visually-hidden">Play video: New Products 11/27/2019 Featuring LPS33HW Water Resistant Pressure Sensor @adafruit #adafruit</span> </a> </lite-youtube></p><p><lite-youtube videoid="z_g93ytDZRM" title="New Products 8/21/19 Featuring #Adafruit 4x4 #NeoTrellis Feather M4 Kit Pack!" style="background-image: url(https://cdn-shop.adafruit.com/ytimg/vi/z_g93ytDZRM/hqdefault.jpg)" params="start=744" > <a href="https://www.youtube.com/watch?v=z_g93ytDZRM&t=744" class="lyt-playbtn" title="Play video"> <span class="lyt-visually-hidden">Play video: New Products 8/21/19 Featuring #Adafruit 4x4 #NeoTrellis Feather M4 Kit Pack!</span> </a> </lite-youtube></p><p><lite-youtube videoid="3XeWrovDFYk" title="New Products 7/17/19 Featuring 2.0" 320x240 Color IPS #TFT Display! #adafruit" style="background-image: url(https://cdn-shop.adafruit.com/ytimg/vi/3XeWrovDFYk/hqdefault.jpg)" params="start=111" > <a href="https://www.youtube.com/watch?v=3XeWrovDFYk&t=111" class="lyt-playbtn" title="Play video"> <span class="lyt-visually-hidden">Play video: New Products 7/17/19 Featuring 2.0" 320x240 Color IPS #TFT Display! #adafruit</span> </a> </lite-youtube></p> </div> </section> <section id="technical-details" class="prod-accordion-content prod-accordion-content-technical-details mobile-text-wrapper" aria-labelledby="tab-technical-details-heading"> <div class="tab-heading-row"> <h2 id="tab-technical-details-heading"> Technical Details </h2> </div> <div id="tab-technical-details-content" class="panel-collapse collapse in"> <div class="row"> <div class="col-lg-12 col-md-12 col-sm-12 col-xs-12"><ul><li>Outer Diameter: ~50.6mm / ~2.0"</li><li>Weight: 8.9g</li></ul><p><strong>Revision History:</strong></p><ul><li><strong>As of Nov 22, 2019 </strong>we updated this design from Alpha to release.
