Circuit Playground Bluefruit is our third board in the Circuit Playground series, another step towards a perfect introduction to electronics and programming. 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!
Here's some of the great goodies baked in to each Circuit Playground Bluefruit:
- Outer Diameter: ~50.6mm / ~2.0"
- Weight: 8.9g
- As of Nov 22, 2019 we updated this design from Alpha to release. The antenna design changed slightly, and we added a pin that allows the user to turn off power to the NeoPixels, microphone, and temperature/light sensor so only the accelerometer is active, for low power usage!
